You probably wouldn’t buy a car without knowing its horsepower. The metric might not matter as much to you as things like fuel efficiency, safety, or spiffy good looks. It might not even matter at all, but it’s still something you want to know before driving off the lot.
Similarly, you probably wouldn’t buy cloud storage without knowing a little bit about how it performs. Whether you need the metaphorical Ferrari of cloud providers, the safety features of a Volvo, or the towing capacity of a semitruck, understanding how each performs can significantly impact your cloud storage decisions. And to understand cloud performance, you have to understand the difference between bandwidth and throughput.
In this blog, I’ll explain what bandwidth and throughput are and how they differ, as well as other key concepts like threading, multi-threading, and throttling—all of which can add more complexity and potential confusion to a cloud storage decision and the efficiency of data transfers.
Bandwidth, Throughput, and Latency: A Primer
Three critical components form the cornerstone of cloud performance: bandwidth, throughput, and latency. To easily understand their impact, imagine the flow of data to water moving through a pipe—an analogy that paints a visual picture of how data travels across a network.
Bandwidth: The diameter of the pipe represents bandwidth. It’s the maximum width that dictates how much water (data) can flow through it at any given time. In technical terms, bandwidth is the data transfer rate that a network connection can support. It’s usually measured in bits per second (bps). A wider pipe (higher bandwidth) means more data can flow, similar to having a multi-lane road where more vehicles can travel side by side.
Throughput: If bandwidth is the pipe’s width, then throughput is the rate at which water moves through the pipe successfully. In the context of data, throughput is the actual data transfer rate that is sent over a network. It is also measured in bits per second (bps). Various factors can affect throughput—such as network traffic, processing power, packet loss, etc. While bandwidth is the potential capacity, throughput is the reality of performance, which is often less than the theoretical maximum due to real-world constraints.
Latency: Now, consider the time it takes for water to start flowing from the pipe’s opening after the tap is turned on. That time delay can be considered as latency. It’s the time it takes for a packet of data to travel from the source to the destination. Latency is crucial in use cases where time is of the essence, and even a slight delay can be detrimental to the user experience.
Understanding how bandwidth, throughput, and latency are interrelated is vital for anyone relying on cloud storage services. Bandwidth sets the stage for potential performance, but it’s the throughput that delivers actual results. Meanwhile, latency is a measure of how long it takes data to be delivered to the end user in real time.
Threading and Multi-Threading in Cloud Storage
When we talk about moving data in the cloud, two concepts often come up: threading and multi-threading. These might sound very technical, but they’re actually pretty straightforward once broken down into simpler terms.
First of all, threads go by many different names. Different applications may refer to them as streams, concurrent threads, parallel threads, concurrent uploads, parallelism, etc. But what all these terms refer to when we’re discussing cloud storage is the process of uploading files. To understand threads, think of a big pipe with a bunch of garden hoses running through it. The garden hose is a single thread in our pipe analogy. The hose carries water (your data) from one point to another—say from your computer to the cloud or vice versa. In simple terms, it’s the pathway your data takes. Each hose represents an individual pathway through which data can move between a storage device and the network.
Cloud storage systems use sophisticated algorithms to manage and prioritize threads. This ensures that resources are allocated efficiently to optimize data flow. Threads can be prioritized based on various criteria such as the type of data being transferred, network conditions, and overall load on the system.
Multi-Threading
Now, imagine: instead of just one garden hose within a pipe, you have several in parallel to each other. This setup is multi-threading. It lets multiple streams of water (data) flow at the same time, significantly speeding up the entire process. In the context of cloud storage, multi-threading enables the simultaneous transfer of multiple data streams, significantly speeding up data upload and download.
Cloud storage takes advantage of multithreading. It can take pretty much as many threads as you can throw at it and its performance should scale accordingly. But it doesn’t do so automatically—because the effectiveness of multi-threading depends on the underlying network infrastructure and the ability of the software to efficiently manage multiple threads.
Chances are most devices can’t handle or take advantage of the maximum number of threads cloud storage can handle as it puts additional load on your network and device. Therefore, it often takes a trial-and-error approach to find the sweet spot to get optimal performance without severely affecting the usability of your device.
Managing Thread Count
Certain applications automatically manage threading and adjust the number of threads for optimal performance. When you’re using cloud storage with an integration like backup software or a network attached storage (NAS) device, the multi-threading setting is typically found in the integration’s settings.
Many backup tools, like Veeam, are already set to multi-thread by default. However, some applications might default to using a single thread unless manually configured otherwise.
That said, there are limitations associated with managing multiple threads. The gains from increasing the number of threads are limited by the bandwidth, processing power, and memory. Additionally, not all tasks are suitable for multi-threading; some processes need to be executed sequentially to maintain data integrity and dependencies between tasks.
In essence, threading is about creating a pathway for your data and multi-threading is about creating multiple pathways to move more data at the same time. This makes storing and accessing files in the cloud much faster and more efficient.
The Role of Throttling
Throttling is the deliberate slowing down of internet speed by service providers. In the pipe analogy, it’s similar to turning down the water flow from a faucet. Service providers use throttling to manage network traffic and prevent the system from becoming overloaded. By controlling the flow, they ensure that no single user or application monopolizes the bandwidth.
Why Do Cloud Service Providers Throttle?
The primary reason cloud service providers would throttle is to maintain an equitable distribution of network resources. During peak usage times, networks can become congested, much like roads during rush hour. Throttling helps manage these peak loads, ensuring all users have access to the network without significant drops in quality or service. It’s a balancing act, aiming to provide a steady, reliable service to as many users as possible.
Scenarios Where Throttling Can Be a Hindrance
While throttling aims to manage network traffic for fairness purposes, it can be frustrating in certain situations. For heavy data users, such as businesses that rely on real-time data access and media teams uploading and downloading large files, throttling can slow operations and impact productivity. Additionally, for services not directly causing any congestion, throttling can seem unnecessary and restrictive.
Do CSPs Have to Throttle?
As a quick plug, Backblaze does not throttle, so customers can take advantage of all their bandwidth while uploading to B2 Cloud Storage. Many other public cloud storage providers do throttle, although they certainly may not make it widely known. If you’re considering a cloud storage provider and your use case demands high throughput or fast transfer times, it’s smart to ask the question upfront.
Optimizing Cloud Storage Performance
Achieving optimal performance in cloud storage involves more than just selecting a service; it requires a clear understanding of how bandwidth, throughput, latency, threading, and throttling interact and affect data transfer. Tailoring these elements to your specific needs can significantly enhance your cloud storage experience.
Balancing bandwidth, throughput, and latency: The key to optimizing cloud performance lies in your use case. For real-time applications like video conferencing or gaming, low latency is crucial, whereas, for backup use cases, high throughput might be more important. Assessing the types of files you’re transferring and their size along with content delivery networks (CDN) can help in optimizing and achieving peak performance.
Effective use of threading and multi-threading: Utilizing multi-threading effectively means understanding when it can be beneficial and when it might lead to diminishing returns. For large file transfers, multi-threading can significantly reduce transfer times. However, for smaller files, the overhead of managing multiple threads might outweigh the benefits. Using tools that automatically adjust the number of threads based on file size and network conditions can offer the best of both worlds.
Navigating throttling for optimal performance: When selecting a cloud storage provider (CSP), it’s crucial to consider their throttling policies. Providers vary in how and when they throttle data transfer speeds, affecting performance. Understanding these policies upfront can help you choose a provider that aligns with your performance needs.
In essence, optimizing cloud storage performance is an ongoing process of adjustment and adaptation. By carefully considering your specific needs, experimenting with settings, and staying informed about your provider’s policies, you can maximize the efficiency and effectiveness of your cloud storage solutions.
Cloud drives like Google Drive, Dropbox, Box, and OneDrive have become the go-to data management solution for countless individuals and organizations. Their appeal lies in the initial free storage offering, user-friendly interface, robust file-sharing, and collaboration tools, making it easier to access files from anywhere with an internet connection.
However, recent developments in the cloud drives space have posed significant challenges for businesses and organizations. Both Google and Microsoft, leading providers in this space, have announced the discontinuation of their unlimited storage plans.
Additionally, it’s essential to note that cloud drives, which are primarily sync services, do not offer comprehensive data protection. Today, we’re exploring how organizations can recognize the limitations of cloud drives and strategize accordingly to safeguard their data without breaking the bank.
Attention Higher Ed
Higher education institutions have embraced platforms like Google Drive, Dropbox, Box, and OneDrive to store vast amounts of data—sometimes reaching into the petabytes. With unlimited plans out the window, they now face the dilemma of either finding alternative storage solutions or deleting data to avoid steep fees. In fact, the education sector reported the highest rates of ransomware attacks with 80% of secondary education providers and 79% of higher education providers hit by ransomware in 2023. If you manage IT for a
Sync vs. Backup: Why Cloud Drives Fall Short on Full Data Security
Cloud Sync
Cloud drives offer users an easy way to store and protect files online, and it might seem like these services back up your data. But, they don’t. These services sync (short for “synchronize”) files or folders on your computer to your other devices running the same application, ensuring that the same and most up-to-date information is merged across each device.
The “live update” feature of cloud drives is a double-edged sword. On one hand, it ensures you’re always working on the latest version of a document. On the other, if you need to go back to a specific version of a file from two weeks ago, you might be out of luck unless you’ve manually saved that version elsewhere.
Another important item to note is that if cloud drives are shared with others, often they can make changes to the content which can result in the data changing or being deleted and without notifying other users. With the complexity of larger organizations, this presents a potential vulnerability, even with well-meaning users and proactive management of drive permissions.
Cloud Backup
Unlike cloud sync tools, backup solutions are all about historical data preservation. They utilize block-level backup technology, which offers granular protection of your data. After an initial full backup, these systems only save the incremental changes that occur in the dataset. This means if you need to recover a file (or an entire system) as it existed at a specific point in time, you can do so with precision. This approach is not only more efficient in terms of storage space but also crucial for data recovery scenarios.
For organizations where data grows exponentially but is also critically important and sensitive, the difference between sync and backup is a crucial divide between being vulnerable and being secure. While cloud drives offer ease of access and collaboration, they fall short in providing the comprehensive data protection that comes from true backup solutions, highlighting the need to identify the gap and choose a solution that better fits your data storage and security goals. A full-scale backup solution will typically include backup software like Veeam, Commvault, and Rubrik, and a storage destination for that data. The backup software allows you to configure the frequency and types of backups, and the backup data is then stored on-premises and/or off-premises. Ideally, at least one copy is stored in the cloud, like Backblaze B2, to provide true off-site, geographically distanced protection.
Lack of Protection Against Ransomware
Ransomware payments hit a record high $1 billion in 2023. It shouldn’t be news to anyone in IT that you need to defend against the evolving threat of ransomware with immutable backups now more than ever. However, cloud drives fall short when it comes to protecting against ransomware.
The Absence of Object Lock
Object Lock serves as a digital vault, making data immutable for a specified period. It creates a virtual air gap, protecting data from modification, manipulation, or deletion, effectively shielding it from ransomware attacks that seek to encrypt files for ransom. Unfortunately, most cloud drives do not incorporate this technology.
Without Object Lock, if a piece of data or a document becomes infected with ransomware before it’s uploaded to the cloud, the version saved on a cloud drive can be compromised as well. This replication of infected files across the cloud environment can escalate a localized ransomware attack into a widespread data disaster.
Other Security Shortcomings
Beyond the absence of Object Lock, cloud drives may also lag in other critical security measures. While many offer some level of encryption, the robustness of this encryption and its effectiveness in protecting data at reset and in transit can vary significantly. Additionally, the implementation of 2FA and other access control measures is not always standard. These gaps in security protocols can leave the door open for unauthorized access and data breaches.
Navigating the Shared Responsibility Model
The shared responsibility model of cloud computing outlines who is responsible for what when it comes to cloud security. However, this model often leads to a sense of false security. Under this model, cloud drives typically take responsibility for the security “of” the cloud, including the infrastructure that runs all of the services offered in the cloud. On the other hand, the customers are responsible for security “in” the cloud. This means customers must manage the security of their own data.
What’s the difference? Let’s use an example. If a user inadvertently uploads a ransomware-infected file to a cloud drive, the service might protect the integrity of the cloud infrastructure, ensuring the malware doesn’t spread to other users. However, the responsibility to prevent the upload of the infected file in the first place, and managing its consequences, falls directly on the user. In essence, while cloud drives provide a platform for storing your data, relying solely on them without understanding the nuances of the shared responsibility model could leave gaps in your data protection strategy.
It’s also important to understand that Google, Microsoft, and Dropbox may not back up your data as often as you’d like, in the format you need, or provide timely, accessible recovery options.
The Limitations of Cloud Drives in Computer Failures
Cloud drives, such as iCloud, Google Drive, Dropbox, and OneDrive, synchronize your files across multiple devices and the cloud, ensuring that the latest version of a file is accessible from anywhere. However, this synchronization does not equate to a full backup of your computer’s data. In the event of a computer failure, only the files you’ve chosen to sync would be recoverable. Other data stored on the computer (but not in the sync folder) would be lost.
While some cloud drives offer versioning, which allows you to recover previous versions of files, this features are often limited in scope and time. It’s not designed to recover all types of files after a hardware failure, which a comprehensive backup solution would allow.
Additionally, users often have to select which folders of files are synchronized, potentially overlooking important data. This selective sync means that not all critical information is protected automatically, unlike with a backup solution that can be set to automatically back up all data.
The Challenges of Data Sprawl in Cloud Drives
Cloud drives make it easy to provision storage for a wide array of end users. From students and faculty in education institutions to teams in corporations, the ease with which users can start storing data is unparalleled. However, this convenience comes with its own set of challenges—and one of the most notable culprits is data sprawl.
Data sprawl refers to the rapid expansion and scattering of data without a cohesive management strategy. It is the accumulation of vast amounts of data to the point where organizations no longer know what data they have or what is happening with that data. Organizations often struggle to get a clear picture of who is storing what, how much space it’s taking up, and whether certain data remains accessed or has become redundant. This can lead to inefficient use of storage resources, increased costs, and potential security risks as outdated or unnecessary information piles up. The lack of sophisticated tools within cloud drive platforms for analyzing and understanding storage usage can significantly complicate data governance and compliance efforts.
The Economic Hurdles of Cloud Drive Pricing
The pricing structure of cloud drive solutions present a significant barrier to achieving both cost efficiency and operational flexibility. The sticker price is only the tip of the iceberg, especially for sprawling organizations like higher education institutions or large enterprises with unique challenges that make the standard pricing models of many cloud drive services less than ideal. Some of the main challenges are:
User-Based Pricing: Cloud drive platforms base their pricing on the number of users, an approach that quickly becomes problematic for large institutions and businesses. With staff and end user turnover, predicting the number of active users at any given time can be a challenge. This leads to overpaying for unused accounts or constantly adjusting pricing tiers to match the current headcount, both of which are administrative headaches.
The High Cost of Scaling: The initial promise of free storage tiers or low-cost entry points fades quickly as institutions hit their storage limits. Beyond these thresholds, prices can escalate dramatically, making budget planning a nightmare. This pricing model is particularly problematic for businesses where data is continually growing. As these data sets expand, the cost to store them grows exponentially, straining already tight budgets.
Limitations of Storage and Users: Most cloud drive platforms come with limits on storage capacity and a cap on the number of users. Upgrading to higher tier plans to accommodate more users or additional storage can be expensive. This often forces organizations into a cycle of constant renegotiation and plan adjustments.
We’re Partial to an Alternative: Backblaze
While cloud drives excel in collaboration and file sharing, they often fall short in delivering the comprehensive data security and backup that businesses and organizations need. However, you are not without options. Cloud storage platforms like Backblaze B2 Cloud Storage secure business and educational data and budgets with immutable, set-and-forget, off-site backups and archives at a fraction of the cost of legacy providers. And, with Universal Data Migration, you can move large amounts of data from cloud drives or any other source to B2 Cloud Storage at no cost to you.
For those who appreciate the user-friendly interfaces of services like Dropbox or Google Drive, Backblaze provides integrations that deliver comparable front-end experiences for ease of use without compromising on security. However, if your priority lies in securing data against threats like ransomware, you can integrate Backblaze B2 with popular backup tools including Veeam, Rubrik, and Commvault, for immutable, virtually air-gapped backups to defend against cyber threats. Backblaze also offers free egress for up to three times your data stored—or unlimited free egress between many of our compute or CDN partners—which means you don’t have to worry about the costs of downloading data from the cloud when necessary.
Beyond Cloud Drives: A Secure, Cost-Effective Approach to Data Storage
In summary, cloud drives offer robust file sharing and collaboration tools, yet businesses and organizations looking for a more secure, reliable, and cost-effective data storage solution have options. By recognizing the limitations of cloud drives and by leveraging the advanced capabilities of cloud backup services, organizations can not only safeguard their data against emerging threats but also ensure it remains accessible and within budget.
Kubernetes, originally embraced by DevOps teams for its seamless application deployment, has become the go-to for businesses looking to deploy and manage applications at scale. This powerful container orchestration platform brings many benefits, but it’s not without risks—data loss, misconfigurations, and systems failures can happen when you least expect them.
That’s why implementing a comprehensive backup strategy is essential for protecting against potential failures that could result in significant downtime, end-user dissatisfaction, and financial losses. However, backing up Kubernetes can be challenging. The environment’s dynamic nature, with containers constantly being created and destroyed, presents a unique set of challenges.
Traditional backup solutions might falter in the face of Kubernetes’s complexities, highlighting the need for specialized approaches to back up the data and the state of your containerized applications. In this guide, let’s explore how to effectively back up and protect your Kubernetes environments against a wide range of threats, from misconfigurations to ransomware.
Understanding Kubernetes Architecture
Kubernetes has a fairly straightforward architecture that is designed to automate the deployment, scaling, and management of application containers across cluster of hosts. Understanding this architecture is not only essential for deploying and managing applications, but also for implementing effective security measures. Here’s a breakdown of Kubernetes hierarchical components and concepts.
Containers: The Foundation of Kubernetes
Containers are lightweight, virtualized environments designed to run application code. They encapsulate an application’s code, libraries, and dependencies into a single object. This makes containerized applications easy to deploy, scale, and manage across different environments.
Pods: The Smallest Deployable Units
Pods are often described as logical hosts that can contain one or multiple containers that share storage, network, and specifications on how to run the containers. They are ephemeral by nature—temporary storage for a container that gets wiped out and lost when the container is stopped or restarted.
Nodes: The Workhorses of Kubernetes
Nodes represent the physical or virtual machines that run the containerized applications. Each node is managed by the master components and contains the services necessary to run pods.
Cluster: The Heart of Kubernetes
A cluster is a collection of nodes that run containerized applications. Clusters provide the high-level structure within which Kubernetes manages the containerized applications. They enable Kubernetes to orchestrate containers’ deployment, scaling, and management across multiple nodes seamlessly.
Control Plane: The Brain Behind the Operation
The control plane is responsible for managing the worker nodes and the pods in the cluster. It includes several components, such as Kubernetes API server, scheduler, controller manager, and etcd (a key-value store for cluster data). The control plane makes global decisions about the cluster, and therefore its security is paramount as it’s the central point of management for the cluster.
What Needs to be Protected in Kubernetes?
In Kubernetes, securing your environment is not just about safeguarding the data; it’s about protecting the entire ecosystem that interacts with and manages the data. Here’s an overview of the key components that require protection.
Workloads and Applications
Containers and Pods: Protecting containers involves securing the container images from vulnerabilities and ensuring runtime security. For pods, it’s crucial to manage security contexts and network policies effectively to prevent unauthorized access and ensure that sensitive data isn’t exposed to other pods or services unintentionally.
Deployments and StatefulSets: These are higher-level constructs that manage the deployment and scaling of pods. Protecting these components involves ensuring that only authorized users can create, update, or delete deployments.
Data and Storage
Persistent Volumes (PVs) and Persistent Volume Claims (PVCs): Persistent storage in Kubernetes is managed through PVs and PVCs, and protecting them is essential to ensure data integrity and confidentiality. This includes securing access to the data they contain, encrypting data at rest and transit, and properly managing storage access permissions.
ConfigMaps and Secrets: While ConfigMaps might contain general configuration settings, secrets are used to store sensitive data such as passwords, OAuth tokens, and SSH keys.
Network Configuration
Services and Ingress: Services in Kubernetes provide a way to expose an application on a set of pods as a network service. Ingress, on the other hand, manages external access to the services within a cluster, typically HTTP. Protecting these components involves securing the communication channels, implementing network policies to restrict access to and from the services, and ensuring that only authorized services are exposed to the outside world.
Network Policies: Network policies define how groups of pods are allowed to communicate with each other and other network endpoints. Securing them is essential for creating a controlled, secure networking environment with your Kubernetes cluster.
Access Controls and User Management
Role-Based Access Control (RBAC): RBAC in Kubernetes helps define who can access what within a cluster. It allows administrators to regulate access to Kubernetes resources and namespaces based on the roles assigned to users. Protecting your cluster with RBAC users and applications having only the access they need while minimizing the potential impact of compromised credentials or insider threats.
Service Accounts: Service accounts provide an identity for processes that run in a pod, allowing them to interact with the Kubernetes API. Managing and securing these accounts is crucial to prevent unauthorized API access, which could lead to data leakage or unauthorized modifications of the cluster state.
Cluster Infrastructure
Nodes and the Control Plane: The nodes run the containerized applications and are controlled by the control plane, which includes the API server, scheduler, controller manager, and etcd database. Securing the nodes involves hardening the underlying operating system (OS), ensuring secure communication between the nodes and the control plane, and protecting control plane components from unauthorized access and tampering.
Kubernetes Secrets Management: Managing secrets securely in Kubernetes is critical for protecting sensitive data. This includes implementing best practices for secrets encryption, both at rest and in transit, and limiting secrets exposure to only those pods that require access.
Protecting these components is crucial for maintaining both the security and operational integrity of your Kubernetes environment. A breach in any of these areas can compromise your entire cluster, leading to data loss and causing service disruption and financial damage. Implementing a layered security approach that addresses the vulnerabilities of the Kubernetes architecture is essential for building a resilient, secure deployment.
Challenges in Kubernetes Data Protection
Securing the Kubernetes components we discussed above poses unique challenges due to the platform’s dynamic nature and the diverse types of workloads it supports. Understanding these challenges is the first step toward developing effective strategies for safeguarding your applications and data. Here are some of the key challenges:
Dynamic Nature of Container Environments
Kubernetes’s fluid landscape, with containers constantly being created and destroyed, makes traditional data protection methods less effective. The rapid pace of change demands backup solutions that can adapt just as quickly to avoid data loss.
Statelessness vs. Statefulness
Stateless Applications: These don’t retain data, pushing the need to safeguard the external persistent storage they rely on.
Stateful Applications: Managing data across sessions involves intricate handling of PVs PVCs, which can be challenging in a system where pods and nodes are frequently changing.
Data Consistency
Maintaining data consistency across distributed replicas in Kubernetes is complex, especially for stateful sets with persistent data needs. Strategies for consistent snapshot or application specific replication are vital to ensure integrity.
Scalability Concerns
The scalability of Kubernetes, while a strength, introduces data protection complexities. As clusters grow, ensuring efficient and scalable backup solutions becomes critical to prevent performance degradation and data loss.
Security and Regulatory Compliance
Ensuring compliance with the appropriate standards—GDPR, HIPAA, or SOC 2 standards, for instance—always requires keeping track of storage and management of sensitive data. In a dynamic environment like Kubernetes, which allows for frequent creation and destruction of containers, enforcing persistent security measures can be a challenge. Also, the sensitive data that needs to be encrypted and protected may be hosted in portions across multiple containers. Therefore, it’s important to not only track what is currently existent but also anticipate possible iterations of the environment by ensuring continuous monitoring and the implementation of robust data management practices.
As you can see, Kubernetes data protection requires navigating its dynamic nature and the dichotomy of stateless and stateful applications while addressing the consistency and scalability challenges. A strategic approach to leveraging Kubernetes-native solutions and best practices is essential for effective data protection.
Choosing the Right Kubernetes Backup Solution: Strategies and Considerations
When it comes to protecting your Kubernetes environments, selecting the right backup solution is important. Solutions like Kasten by Veeam, Rubrik, and Commvault are some of the top Kubernetes container backup solutions that offer robust support for Kubernetes backup.
Here are some essential strategies and considerations for choosing a solution that supports your needs.
Assess Your Workload Types: Different applications demand different backup strategies. Stateful applications, in particular, require backup solutions that can handle persistent storage effectively.
Evaluate Data Consistency Needs: Opt for backup solutions that offer consistent backup capabilities, especially for databases and applications requiring strict data consistency. Look for features that support application-consistent backups, ensuring that data is in a usable state when restored.
Scalability and Performance: The backup solution should seamlessly scale with your Kubernetes deployment without impacting performance. Consider solutions that offer efficient data deduplication, compressions, and incremental backup capabilities to handle growing data volumes.
Recovery Objectives: Define clear recovery objectives. Look for solutions that offer granular recovery options, minimizing downtime by allowing for precise restoration of applications or data, aligning with recovery time objectives (RTOs) and recovery point objectives (RPOs).
Integration and Automation: Choose a backup solution that integrates well or natively with Kubernetes, offering automation capabilities for backup schedules, policy management, and recovery processes. This integration simplifies operations and enhances reliability.
Vendor Support and Community: Consider the vendor’s reputation, the level of support provided, and the solution’s community engagement. A strong support system and active community can be invaluable for troubleshooting and best practices.
By considering the above strategies and the unique features offered by backup solutions, you can ensure your Kubernetes environment is not only protected against data loss but also aligned with your operational dynamics and business objectives.
Leveraging Cloud Storage for Comprehensive Kubernetes Data Protection
After choosing a Kubernetes backup application, integrating cloud storage such as Backblaze B2 with your application offers a flexible, secure, scalable approach to data protection. By leveraging cloud storage solutions, organizations can enhance their Kubernetes data protection strategy, ensuring data durability and availability across a distributed environment. This integration facilitates off-site backups, which are essential for disaster recovery and compliance with data protection policies, providing a robust layer of security against data loss, configuration errors, and breaches.
Protect Your Kubernetes Data
In summary, understanding the intricacies of Kubernetes components, acknowledging the challenges in Kubernetes backup, selecting the appropriate backup solution, and effectively integrating cloud storage are pivotal steps in crafting a comprehensive Kubernetes backup strategy. These measures ensure data protection, operational continuity, and compliance. The right backup solution, tailored to Kubernetes’s distinctive needs, coupled with the scalability and resiliency of cloud storage, provides a robust framework for safeguarding against data loss or breaches. This multi-faceted approach not only safeguards critical data but also supports the agility and scalability that modern IT environments demand.
There’s only one truth you need to know about tech: at some point, it will fail. Hard drives die. You get the blue screen of death the day of the big presentation. You lose cell service right when your mom calls. (Or maybe you pretend to lose service right when your mom calls. We won’t judge.) Whatever it is, we’ve all been there.
If you use network attached storage (NAS) for your business or at home, you’re probably well aware of this fact. The redundancy you get from a solid RAID configuration might be one of the reasons you invested in a NAS—to prepare for inevitable drive failures. NAS devices are a great investment for a business for their durability and reliability, but there are things you can do to extend the lifespan of your NAS and get even more out of your investment.
Extending the lifespan of a NAS system isn’t just about preventing hardware failures; it’s crucial for ensuring uninterrupted access to critical data while maximizing ROI on your IT investments. In this blog, you’ll learn about the key factors that influence NAS longevity and get real-world strategies to strengthen and optimize your NAS infrastructure.
Understanding NAS Lifespan
Today’s NAS devices offer faster processing, enhanced performance, and significantly larger storage capabilities than ever before. These technological advancements have paved the way for efficient local data management using NAS in both professional and personal settings.
Despite these advancements, it’s important to acknowledge that NAS devices tend to have a finite lifespan. This limitation is due to several factors, including the physical wear and tear of hardware components, ever-evolving software requirements, and the constant advancement of technology which can render older systems less efficient or incompatible with new standards.
Also, it’s crucial to differentiate between the life expectancy of a NAS device and that of the hard drives within the device. While the NAS itself may continue to function, the hard drives that are subjected to intense read/write operations often have a shorter lifespan. If you want to learn more about hard drive reliability and failure rates, refer to Backblaze’s Hard Drive Stats.
Key Factors Affecting NAS Longevity
From the quality of the hardware to the environment it operates in, multiple elements contribute to the lifespan of NAS. Let’s explore these key factors in detail:
1. Hardware Components: Quality and Durability
One of the key factors that heavily affects the NAS device is the quality of the hardware itself. Additionally, factors such as the processor, memory, and power unit also play crucial roles. High-quality hardware and components from reputable manufacturers tend to last longer and offer better performance and reliability which contribute to the overall lifespan of the NAS.
2. Workload and Usage Intensity
The workload handled by the NAS is a significant determinant of its longevity. Devices that are constantly under heavy load, managing large data transfers, or running intensive applications will likely experience wear and tear more rapidly than those used for lighter tasks.
3. Environmental Factors: Temperature, Humidity, and Corrosion
Operating a NAS in environments with high temperatures or humidity levels can lead to overheating and moisture-related damage. Additionally, locations with high levels of dust or corrosive elements can lead to physical deterioration of components.
4. Quality of Network Environment
The quality and stability of the network environment in which the NAS operates can also affect its lifespan. Frequent network issues or unstable connections can strain the NAS’s hardware and software, potentially leading to earlier failures.
5. Support, Technological Advancements, and Compatibility
Ongoing support and compatibility with new technologies are also vital for the longevity of NAS systems. As technology evolves, older NAS devices may struggle with compatibility issues, rendering them less efficient or even obsolete.
Maintenance and Care for Enhanced Lifespan
Now that we understand the factors that affect NAS longevity, let’s explore how proactive maintenance and care are crucial to extending its lifespan. There are a number of things you can do to keep your NAS functioning properly for the long haul:
Regular Maintenance: Routine cleaning is vital for maintaining NAS efficiency. Dust accumulation can lead to overheating. Regularly cleaning the external vents and fans, and ensuring the device is in a well-ventilated area can prevent thermal issues and prolong the device’s life.
Proactive Drive Replacements: Hard drives are among the most failure-prone components in a NAS. Implementing a regular schedule to check drive health and replacing unhealthy or borderline drives proactively can prevent data loss and reduce the workload on the NAS’s remaining drives, thus preserving its overall integrity.
Updating Software and Patches: Keeping the NAS software and firmware up to date is essential for security and performance. Regular updates often include patches for vulnerabilities, performance enhancements, and new features that can improve the efficiency and longevity of the NAS.
Monitoring NAS Health: Utilizing the tools and built-in functionalities to monitor the health and performance of your NAS also helps extend its lifespan. Many NAS systems come with software that can alert you to issues such as failing drives, high temperatures, or network problems. Keeping an eye on these metrics can help you address potential problems before they escalate.
Environmental Considerations: The operating environment of a NAS plays a significant role in NAS longevity. Keeping your NAS in a stable environment with controlled temperature and humidity levels should be considered to extend its lifespan.
Power Protection: Protect your NAS from power surges and outages using uninterrupted power supply (UPS). This can not only prevent data loss but also help avoid any potential hardware damage caused by electrical issues.
The CyberPower 900 AVR is just one example of a UPS. Source.
Recognizing When to Replace the NAS: Look out for indicators that suggest it’s time to replace your NAS. These include the expiration of the manufacturer’s warranty, noticeable performance declines, increased frequency of repairs, or when the device no longer meets your evolving storage needs. Waiting until a complete failure can be more costly and disruptive.
By adhering to these maintenance and care guidelines, you can significantly enhance the lifespan and reliability of your NAS, ensuring that it continues to serve as a robust and efficient data storage solution for your business or personal needs.
Implementing Fault Tolerance and Off-Loading Data to Cloud
In addition to proactive maintenance and care, there are a few other strategies you can use to extend NAS lifespan such as implementing fault tolerance and adding cloud storage to your backup strategy to offload data from your NAS. Let’s explore them below.
The Importance of Fault Tolerance and RAID Configurations in NAS
Fault tolerance refers to the ability of a NAS to continue operating correctly even if one or more of its hard drives fail. It’s critical for NAS systems to have fault tolerance in place, especially in business environments where data availability and integrity can not be compromised.
RAID (Redundant Array of Independent Disks) plays a pivotal role in achieving fault tolerance. It involves combining multiple hard drives into a single system to improve data redundancy and performance. By doing so, RAID protects against data loss due to single or multiple disk failures, depending on the RAID level implemented.

RAID Configurations
Various RAID configurations offer different balances of data protection, storage efficiency, and performance. Common configurations include RAID 0 (striping), RAID 1 (mirroring), RAID 5 and RAID 6, each with its specific advantages and use cases. For example, RAID 1 is simple and offers data redundancy, while RAID 5 and 6 provide a good balance between storage capacity and data protection. To fully understand which RAID configuration suits your needs, explore our NAS RAID Levels blog which explains how to choose the right RAID level for your NAS data.
Off-Loading and Backing Up NAS Data to the Cloud
Off-loading data from your NAS to a cloud storage service can significantly reduce the workload on your NAS hardware, thus potentially extending its life. You can consider creating a cloud archive of old data and a system for off-loading data on a regular cadence or as projects close.
The cloud also helps you establish a robust 3-2-1 backup strategy (three total copies of your data, two of which are local but on different mediums, and one copy off-site). This ensures data redundancy and offers enhanced data protection against local disasters, theft, or hardware failure. Many NAS devices, like Synology and QNAP, have built-in backup utilities that back up directly to cloud storage like Backblaze B2.
By integrating fault tolerance through RAID configurations and backing up data to the cloud, you can significantly enhance the data protection capabilities of your NAS. This approach not only ensures data safety but also contributes to the overall health and longevity of your NAS system.
Extending Your NAS Lifespan
Navigating the complexities of NAS systems can be a journey full of learning and adaptation. While NAS offers unparalleled convenience of local storage, it’s essential to recognize that its longevity relies on more than just its initial setup. It requires a proactive approach with diligent maintenance while embracing technological advancements such as fault tolerance and RAID levels. When properly cared for, however, many users find NAS to be a long-lived piece of their tech stack.
But, it doesn’t have to stop there. The integration of cloud storage with NAS systems can significantly help reduce the strain on your local system, and safeguard your NAS data off-site while ensuring you have comprehensive 3-2-1 data protection in place.

Upgrading to a network attached storage (NAS) device puts your data in the digital fast lane. If you’re using one, it’s likely because you want to keep your data close to you, ensuring quick access whenever it’s needed. NAS devices, acting as centralized storage systems connected to local networks, offer a convenient way to access data in just a few clicks.
However, as the volume of data on the NAS increases, its performance can tank. You need to know how to keep your NAS operating at its best, especially with growing data demand.
In this blog, you’ll learn about various factors that can affect NAS performance, as well as practical steps you can take to address these issues, ensuring optimal speed, reliability, and longevity for your NAS device.
Why NAS Performance Matters
NAS devices can function as extended hard disks, virtual file cabinets, or centralized local storage solutions, depending on individual needs.
While NAS offers a convenient way to store data locally, storing the data alone isn’t enough. How quickly and reliably you can access your data can make all the difference if you want an efficient workflow. For example, imagine working on a critical project with your team and facing slow file transfers, or streaming a video on a Zoom call only for it to stutter or buffer continuously.
All these can be a direct result of NAS performance issues, and an increase in stored data can directly undermine the device’s performance. Therefore, ensuring optimal performance isn’t just a technical concern, it’s also a concern that directly affects user experience, productivity, and collaboration.
So, let’s talk about what could potentially cause performance issues and how to enhance your NAS.
Common NAS Performance Issues
NAS performance can be influenced by a variety of factors. Here are some of the most common factors that can impact the performance of a NAS device.
Hardware Limitations:
Insufficient RAM: Especially in tasks like media streaming or handling large files, having inadequate memory can slow down operations.
Slow CPU: An underpowered processor can become a bottleneck when multiple users access the NAS at once or during collaboration with team members.
Drive Speed and Type: Hard disk drives (HDDs) are generally slower compared to solid state drives (SSDs), and your NAS can have either type. If your NAS mainly serves as a hub for storing and sharing files, a conventional HDD should meet your requirements. However, for those seeking enhanced speed and performance, SSDs deliver the performance you need.
Outdated Hardware: Older NAS models might not be equipped to handle modern data demands or the latest software.
Software Limitations:
Outdated Firmware/Software: Not updating to the latest firmware or software can lead to performance issues, or to missing out on optimization and security features.
Misconfigured Settings: Incorrect settings can impact performance. This includes improper RAID configuration or network settings.
Background Processes: Certain background tasks, like indexing or backups, can also slow down the system when running.
Network Challenges:
Bandwidth Limitations: A slow network connection, especially on a Wi-Fi network can limit data transfer rates.
Network Traffic: High traffic on the network can cause congestion, reducing the speed at which data can be accessed or transferred.
Disk Health and Configuration:
Disk Failures: A failing disk in the NAS can slow down performance and also poses data loss risk.
Suboptimal RAID Configuration: Some RAID configurations prioritize redundancy more than performance, which can affect the data storage and access speeds.
External Factors:
Simultaneous User Access: If multiple users are accessing, reading, or writing to the NAS simultaneously, it can strain the system, especially if the hardware isn’t optimized to such traffic from multiple users.
Inadequate Power Supply: Fluctuating or inadequate power can cause the NAS to malfunction or reduce its performance.
Operating Temperature: Additionally, if the NAS is in a hot environment, it might overheat and impact the performance of the device.
Practical Solutions for Optimizing NAS Performance
Understanding the common performance issues with NAS devices is the first critical step. However, simply identifying these issues alone isn’t enough. It’s vital to understand practical ways to optimize your existing NAS setup so you can enhance its speed, efficiency, and reliability. Let’s explore how to optimize your NAS.
Performance Enhancement 1: Upgrading Hardware
There are a few different things you can do on a hardware level to enhance NAS performance. First, adding more RAM can significantly improve performance, especially if multiple tasks or users are accessing the NAS simultaneously.
You can also consider switching to SSDs. While they can be more expensive, SSDs offer faster read/write speeds than traditional HDDs, and they store data in flash memory, which means that they retain information even without power.
Finally, you could upgrade the CPU. For NAS devices that support it, a more powerful CPU can better handle multiple simultaneous requests and complex tasks.
Remember to always keep your NAS operating system and software up-to-date to benefit from the latest performance optimizations and security patches. Schedule tasks like indexing, backups or antivirus scans during off-peak hours to ensure they don’t impact user access during high-traffic times. You also need to make sure you’re using the right RAID configuration for your needs. RAID 5 or RAID 6, for example, can offer a good balance between redundancy and performance.
Performance Enhancement 3: Network Enhancements
Consider moving to faster network protocols, like 10Gb ethernet, or ensuring that your router and switches can handle high traffic. Wherever possible, use wired connections instead of Wi-Fi to connect to the NAS for more stable and faster data access and transfer. And, regularly review and adjust network settings for optimal performance. If you can, it also helps to limit simultaneous access. If possible, manage peak loads by setting up access priorities.
Performance Enhancement 4: Regular Maintenance
Use your NAS device’s built-in tools or third-party software to monitor the health of your disks and replace any that show signs of failure. And, keep the physical environment around your NAS device clean, cool, and well ventilated to prevent overheating.
Leveraging the Cloud for NAS Optimization
After taking the necessary steps to optimize your NAS for improved performance and reliability, it’s worth considering leveraging the cloud to further enhance the performance. While NAS offers convenient local storage, it can sometimes fall short when it comes to scalability, accessibility from different locations, and seamless collaboration. Here’s where cloud storage comes into play.
At its core, cloud storage is a service model in which data is maintained, managed, and backed up remotely, and made available to users over the internet. Instead of relying solely on local storage solutions such as NAS or a server, you utilize the vast infrastructure of data centers across the globe to store your data not just in one physical location, but across multiple secure and redundant environments.
As an off-site storage solution for NAS, the cloud not only completes your 3-2-1 backup plan, but can also amplify its performance. Let’s take a look at how integrating cloud storage can help optimize your NAS.
Off-Loading and Archiving: One of the most straightforward approaches is to move infrequently accessed or archival data from the NAS to the cloud. This frees up space on the NAS, ensuring it runs smoothly, while optimizing the NAS by only keeping data that’s frequently accessed or essential.
Caching: Some advanced NAS systems can cache frequently accessed data in the cloud. This means that the most commonly used data can be quickly retrieved, enhancing user experience and reducing the load on the NAS device.
Redundancy and Disaster Recovery: Instead of duplicating data on multiple NAS devices for redundancy, which can be costly and still vulnerable to local disasters, the data can be backed up to the cloud. In case of NAS failure or catastrophic event, the data can be quickly restored from the cloud, ensuring minimal downtime.
Remote Access and Collaboration: While NAS devices can offer remote access, integrating them with cloud storage can streamline this process, often offering a more user-friendly interface and better speeds. This is especially useful for collaborative environments where multiple users work together on files and projects.
Scaling Without Hardware Constraints: As your data volume grows, expanding a NAS can involve purchasing additional drives or even new devices. With cloud integration, you can expand your storage capacity without these immediate hardware investments, eliminating or delaying the need for physical upgrades and extending the lifespan of your NAS.
In essence, integrating cloud storage solutions with your NAS can create a comprehensive system that addresses the shortcomings of NAS devices, helping you create a hybrid setup that offers the best of both worlds: the speed and accessibility of local storage, and the flexibility and scalability of the cloud.
Getting the Best From Your NAS
At its core, NAS offers an unparalleled convenience of localized storage. However, it’s not without challenges, especially when performance issues come into play. Addressing these challenges requires a blend of hardware optimization, software updates, and smart data management settings.
But, it doesn’t have to stop at your local network. Cloud storage can be leveraged effectively to optimize your NAS. It doesn’t just act as a safety net by storing your NAS data off-site, it also makes collaboration easier with dispersed teams and further optimizes NAS performance.
Now, it’s time to hear from you. Have you encountered any NAS performance issues? What measures have you taken to optimize your NAS? Share your experiences and insights in the comments below.
The terms NAS and SAN can be confusing—the technology is similar and, making matters worse, the acronyms are the reverse of each other. NAS stands for network attached storage and SAN stands for storage area network. They were both developed to solve the problem of making stored data available to many users at once. But, they couldn’t be more different in how they achieve that goal.
The TL/DR:
NAS is a single storage device that serves files over ethernet and is relatively inexpensive. NAS devices are easier for a home user or small business to set up.
A SAN is a tightly coupled network of multiple devices that is more expensive and complex to set up and manage. A SAN is better suited for larger businesses and requires administration by IT staff.
Read on and we’ll dissect the nuances of NAS and SANs to help you make informed decisions about which solution best suits your storage needs.
Check Out Our New Technical Documentation Portal
When you’re working on a storage project, you need to be able to find instructions about the tools you’re using quickly. And, it helps if those instructions are easy to use, easy to understand, and easy to share. Our Technical Documentation Portal has been completely overhauled to deliver on-demand content in a user-friendly way so you can find the information you need. Check out the NAS section, including all of our Integration Guides.
Basic Definitions: What Is NAS?
NAS is a device or devices with a large data storage capacity that provides file-based data storage services to other devices on a network. Usually, they also have a client or web portal interface that’s easy to navigate, as well as services like QNAP’s Hybrid Backup Sync or Synology’s Hyper Backup to help manage your files. In other words, NAS is synonymous with user-friendly file sharing.
NAS with eight drive bays for 3.5″ disk drives.
At its core, NAS operates as a standalone device connected to a network, offering shared access to files and folders. NAS volumes appear to the user as network-mounted volumes. The files to be served are typically contained on one or more hard drives in the system, often arranged in RAID arrays. Generally, the more drive bays available within the NAS, the larger and more flexible storage options you have.
Key Characteristics of NAS:
File-Level Access: NAS provides file-level access, ideal for environments where collaborative work and content sharing are paramount.
Simplicity: NAS solutions offer straightforward setups and intuitive interfaces, making them accessible to users with varying levels of technical expertise.
Scalability: While NAS devices can be expanded by adding more drives, there may be limitations in terms of performance and scalability for large-scale enterprise use.
How NAS Works
The NAS device itself is a network node—much like computers and other TCP/IP devices, all of which maintain their own IP address—and the NAS file service uses the ethernet network to send and receive files. This system employs protocols like network file system (NFS) and server message block (SMB), enabling seamless data exchange between multiple users.
The NAS system and clients connect via your local network—all file service occurs via ethernet.
Benefits of NAS
NAS devices are designed to be easy to manage, making them a popular choice for home users, small businesses, and departments seeking straightforward centralized storage. They offer an easy way for multiple users in multiple locations to access data, which is valuable when users are collaborating on projects or need to share information.
For individual home users, if you’re currently using external hard drives or direct attached storage, which can be vulnerable to drive failure, upgrading to a NAS ensures your data is better protected.
For small business or departments, installing NAS is typically driven by the desire to share files locally and remotely, have files available 24/7, achieve data redundancy, have the ability to replace and upgrade hard drives in the system, and most importantly, support integrations with cloud storage that provide a location for necessary automatic data backups.
NAS offers robust access controls and security mechanisms to facilitate collaborative efforts. Moreover, it empowers non-technical individuals to oversee and manage data access through an embedded web server. Its built-in redundancy, often achieved through RAID configurations, ensures solid data resilience. This technology merges multiple drives into a cohesive unit, mimicking a single, expansive volume capable of withstanding the failure of a subset of its constituent drives.
Summary of NAS Benefits:
Relatively inexpensive.
A self-contained solution.
Easy administration.
Remote data availability and 24/7 access.
Wide array of systems and sizes to choose from.
Drive failure-tolerant storage volumes.
Automatic backups to other devices and the cloud.
Limitations of NAS
The weaknesses of NAS primarily revolve around scalability and performance. If more users need access, the server might struggle to keep pace. If you overprovisioned your NAS, you may be able to add storage. But sooner or later you’ll need to upgrade to a more powerful system with a bigger on-board processor, more memory, and faster and larger network connections.
Another drawback ties back to ethernet’s inherent nature. Ethernet divides data into packets, forwarding them to their destination. Yet, depending on network traffic or other issues, potential delays or disorder in packet transmission can hinder file availability until all packets arrive and are put back in order.
Although minor latency (slowness) is not usually noticed by users for small files, in data-intensive domains like video production, where large files are at play, even milliseconds of latency can disrupt operations, particularly video editing workflows.
Basic Definitions: What Is a SAN?
On the other end of the spectrum, SANs are engineered for high-performance and mission-critical applications. They function by connecting multiple storage devices, such as disk arrays or tape libraries, to a dedicated network that is separate from the main local area network (LAN). This isolation ensures that storage traffic doesn’t interfere with regular network traffic, leading to optimized performance and data availability.
Unlike NAS, a SAN operates at the block level, allowing servers to access storage blocks directly. This architecture is optimized for data-intensive tasks like database management and virtualization or video editing, where low latency and consistent high-speed access are essential.
Key Characteristics of SANs:
Block-Level Access: SANs provide direct access to storage blocks, which is advantageous for applications requiring fast, low-latency data retrieval.
Performance: SANs are designed to meet the rigorous demands of enterprise-level applications, ensuring reliable and high-speed data access.
Scalability: SANs offer greater scalability by connecting multiple storage devices, making them suitable for businesses with expanding storage needs.
How Does a SAN Work?
A SAN is built from a combination of servers and storage over a high speed, low latency interconnect that allows direct Fibre Channel (FC) connections from the client to the storage volume to provide the fastest possible performance. The SAN may also require a separate, private ethernet network between the server and clients to keep the file request traffic out of the FC network for even more performance.
By joining together the clients, SAN server, and storage on a FC network, the SAN volumes appear and perform as if it were a directly connected hard drive. Storage traffic over FC avoids the TCP/IP packetization and latency issues, as well as any LAN congestion, ensuring the highest access speed available for media and mission critical stored data.
The SAN management server, storage arrays, and clients all connect via a FC network—all file serving occurs over Fibre Channel.
Benefits of a SAN
Because it’s considerably more complex and expensive than NAS, a SAN is typically used by businesses versus individuals and typically requires administration by an IT staff.
The primary strength of a SAN is that it allows simultaneous shared access to shared storage that becomes faster with the addition of storage controllers. SANs are optimized for data-intensive applications. For example, hundreds of video editors can simultaneously access tens of GB per second of storage simultaneously without straining the network.
SANs can be easily expanded by adding more storage devices, making them suitable for growing storage needs. Storage resources can be efficiently managed and allocated from a central location. SANs also typically include redundancy and fault tolerance mechanisms to ensure data integrity and availability.
Summary of a SAN’s Benefits:
Extremely fast data access with low latency.
Relieves stress on a local area network.
Can be scaled up to the limits of the interconnect.
Operating system level (“native”) access to files.
Often the only solution for demanding applications requiring concurrent shared access.
Limitations of a SAN
The challenge of a SAN can be summed up in its cost and administration requirements—having to dedicate and maintain both a separate ethernet network for metadata file requests and implement a FC network can be a considerable investment. That being said, a SAN is often the only way to provide very fast data access for a large number of users that also can scale to supporting hundreds of users at the same time.

Choosing the Right Solution
When considering a NAS device or a SAN, you might find it helpful to think of it this way: NAS is simple to set up, easy to administer, and great for general purpose applications. Meanwhile, a SAN can be more challenging to set up and administer, but it’s often the only way to make shared storage available for mission critical and high performance applications.
The choice between a NAS device and a SAN hinges on understanding your unique storage requirements and workloads. NAS is an excellent choice for environments prioritizing collaborative sharing and simple management. In contrast, a SAN shines when performance and scalability are top priorities, particularly for businesses dealing with data-heavy applications.
Ultimately, the decision should factor in aspects such as budget, anticipated growth, workload demands, and the expertise of your IT team. Striking the right balance between ease of use, performance, and scalability will help ensure your chosen storage solution aligns seamlessly with your goals.
Are You Using NAS, a SAN, or Both?
If you are using a NAS device or a SAN, we’d love to hear from you about what you’re using and how you’re using them in the comments.
You probably invested in a network attached storage (NAS) device to centralize your storage, manage data more efficiently, and implement on-site backups. So, keeping that data safe is important to you. Unfortunately, as NAS devices have risen in popularity, cybercriminals have taken notice.
Recent high-profile ransomware campaigns have targeted vast numbers of NAS devices worldwide. These malicious attacks can lock away users’ NAS data, holding it hostage until a ransom is paid—or the user risks losing all their data.
If you are a NAS user, learning how to secure your NAS device against ransomware attacks is critical if you want to protect your data. In this guide, you’ll learn why NAS devices are attractive targets for ransomware and how to safeguard your NAS device from ransomware attacks. Let’s get started.
What Is Ransomware?
To begin, let’s quickly understand what ransomware actually is. Ransomware is a type of malicious software or malware that infiltrates systems and encrypts files. Upon successful infection, ransomware denies users access to their files or systems, effectively holding data hostage.
Its name derives from its primary purpose—to demand a “ransom” from the victim in exchange for restoring access to their data. Ransomware actors often threaten to delete, sell, or leak data if the ransom is not paid.
Ransomware threat messages often imitate law enforcement agencies, claiming that the user violated laws and must pay a fine. Other times, it’s a blunt threat—pay or lose your data forever. This manipulative strategy preys on fears and urgency, often pressuring the unprepared victims into paying the ransom.
The consequences of a ransomware attack can be severe. The most immediate impact is data loss, which can be catastrophic if the encrypted files contain sensitive or critical information. There’s also the financial loss from the ransom payment itself which can range from a few hundred dollars to several million dollars.
Moreover, an attack can cause significant operational downtime, with systems unavailable while the malware is removed and data is restored. For businesses, especially the unprepared, the downtime can be disastrous, leading to substantial revenue loss.
Cybersecurity Ventures expects that by 2031, businesses will fall victim to a ransomware attack every other second. Source.
However, the damage doesn’t stop there. The reputational damage caused by a ransomware attack can make customers, partners, and stakeholders lose trust in a business that falls victim to such an attack, especially if it results in a data breach.
As you can see, ransomware is not just malicious code that disrupts your business, it can cause significant harm on multiple fronts. Therefore, it’s important to understand the basics of ransomware as the first step in building a robust defense strategy for your NAS device.
Types of Ransomware
While the modus operandi of ransomware—to deny access to users’ data and demand ransom—remains relatively constant, there are multiple ransomware variants, each with unique characteristics.
Some of the most common types of ransomware include:
Locker Ransomware
Locker ransomware takes an all-or-nothing approach. It locks users out of their entire system, preventing them from accessing any files, applications, or even the operating system itself.
The only thing the users can access is a ransomware note, demanding payment in exchange for restoring access to their system.
Crypto Ransomware
As its name suggests, crypto ransomware encrypts the users’ files and makes them inaccessible. This type of ransomware does not lock the entire system, but rather targets specific file types such as documents, spreadsheets, and multimedia files. The victims can still use their system but cannot access or open the encrypted files without the encryption key.
Ransomware as a Service (RaaS)
RaaS represents a new business model in the dark world of cybercrime. It is essentially a cloud-based platform where ransomware developers sell or rent their ransomware codes to other cybercriminals, who then distribute and manage the ransomware attacks. The ransomware developers receive a cut of the ransom payments.
Leakware
Leakware steals sensitive or confidential information and threatens to publicize them if ransom is not paid. This type of ransomware is particularly damaging as even if the ransom is paid and the data is not leaked, the mere fact that the data was accessed can have significant legal and reputational implications.
Only 4% of victims who paid ransoms actually got all of their data back. Source.
Scareware
Scareware uses social engineering to trick victims into believing that their system is infected with viruses or other malware. They scare people into visiting spoofed or infected websites or downloading malicious software (malware). While not as directly damaging as other forms of ransomware, scareware can be used as the gateway to a more intricate cyberattack and may not be an attack in and of itself.
Can Ransomware Attack NAS?
Yes, ransomware can and frequently does target NAS devices. These storage solutions, while highly effective and efficient, have certain characteristics that make them attractive to cybercriminals.
Let’s explore some of these reasons in more detail below.
Centralized Storage
NAS devices act as centralized storage locations with all data stored in one place. This makes them an attractive target for ransomware attacks. By infiltrating a single NAS device, bad actors can gain access to a significant amount of company data, maximizing the impact of their attack and the potential ransom.
Security Vulnerabilities
Unlike traditional PCs or servers, NAS devices often lack robust security measures. Most NAS systems may not have an antivirus installed, leaving them exposed to various forms of malware including ransomware. Additionally, outdated firmware can further weaken the device’s defenses, offering potential loopholes for attackers to exploit.
Always Online
NAS devices are designed to be continuously online, allowing for convenient and seamless data access. However, this also means they are constantly exposed to the internet, making them a target for online threats around the clock.
Default Configuration Settings
NAS devices, like many other hardware devices, often come with default configurations that prioritize ease of access over security. For example, they may have simple, easy-to-guess default passwords or open access permissions for all users. Not changing these default settings can leave the devices vulnerable to attacks.
Risk Factors: The Human Element
NAS devices are an easy-to-use, accessible way to expand on-site storage and manage data, making them attractive for people without an IT background to use. However, novice users, and even many of your smartest power users, may not know to follow key best practices to prevent ransomware. As humans, all of us are vulnerable to error. In addition to NAS devices having some unique characteristics that make them prime targets for cybercriminals, you can’t discount the human element in ransomware protection. Understanding the following risks can help you shore up your defenses:
Lack of User Awareness
There is often a lack of awareness among NAS users about the potential security risks associated with these devices. Most users may not realize the importance of regularly updating their NAS systems or implementing security measures. This can result in NAS devices being unprotected, making them easy prey for ransomware attacks.
Insufficient Backup Practices
While NAS devices provide local data storage, it has to be noted that they are not a full 3-2-1 backup solution. Data on NAS devices needs to be backed up off-site to protect against hardware failures, theft, natural disasters, and ransomware attacks. If users don’t have an off-site backup, they risk losing all their data or paying a huge ransom to get access to their NAS data.
Lack of Regular Audits
Conducting regular security checks and audits can help identify and rectify any potential vulnerabilities. But, most NAS users take regular security audits as an afterthought and let security gaps go unnoticed and unaddressed.
Uncontrolled User Access
In some organizations, NAS devices may be accessed by numerous employees, some of whom may not be trained in security best practices. This can increase the chances of ransomware attacks via tactics like phishing emails.
Up to 70% of phishing emails are opened by the recipient. Source.
Neglected Software Updates
NAS device manufacturers often release software updates that include patches for security vulnerabilities. If users neglect to regularly update the software on their NAS devices, they can leave the devices exposed to ransomware attacks that exploit those vulnerabilities.
How Do I Protect My NAS From Ransomware?
Now that you understand the NAS devices vulnerabilities and threats that expose them to ransomware attacks, let’s take a look at some of the practical measures that you can take to protect your NAS from these attacks.
Update regularly: One of the most straightforward yet effective measures you can take is to keep your NAS devices’ applications up-to-date. This includes applying patches, firmware, and operating system updates as soon as they’re available and released by your NAS device manufacturer or backup application provider. These updates often contain security enhancements and fixes for vulnerabilities that could otherwise be exploited by ransomware.
Use strong credentials: Make sure all user accounts, especially admin accounts, are protected by strong, unique passwords. Strong credentials are a simple but effective way to avoid falling victim to brute force attacks that use a trial and error method to crack passwords.
Disable default admin accounts: Like we discussed above, most NAS devices come with default admin accounts with well-known usernames and passwords, making them easy targets for attackers. It’s a good idea to disable all these default accounts or change their credentials.
Limit access to NAS: Most businesses provide wide open access to all their users to access NAS data. However, chances are that not every user needs access to every file on your NAS. Limiting access based on user roles and responsibilities can minimize the potential impact in case of a ransomware attack.
Create different user access levels: Along the same lines of limiting access, consider creating different levels of user access. This can prevent a ransomware infection from spreading if a user with a lower level of access falls victim to an attack.
Block suspicious IP addresses: Consider utilizing network security tools to monitor and block IP addresses that have made multiple failed login attempts and/or seem suspicious. This can help prevent brute force attacks.
Implement a firewall and intrusion detection system: Firewalls can prevent unauthorized access to your NAS, while intrusion detection systems can alert you to any potential security breaches. Both can be crucial ways of defense against ransomware.
Adopt the 3-2-1 backup rule with Object Lock: Like we discussed above, NAS devices offer a centralized storage solution that is local, fast, and easy to share. However, NAS is not a backup solution as it doesn’t protect your data from theft, natural disasters, or hardware failures. Therefore, it’s essential to implement a 3-2-1 backup strategy, where three copies of your data is stored on two different types of storage with one copy stored off-site. This can ensure that you have a secure and uninfected backup even if your NAS is hit by ransomware. The Object Lock feature, available with cloud storage providers such as Backblaze, prevents data from being deleted, ensuring your backup remains intact even in the event of a ransomware attack.
The Role of Cybersecurity Training
While technical measures are a crucial part of NAS ransomware protection, they are only as effective as the people who use them. Human error is often cited as one of the leading causes of successful cyber-attacks, including ransomware.
This is where cybersecurity training comes in, playing an important role in helping individuals identify and avoid threats.
Studies have shown that in 93% of cases, an external attacker can breach an organizations network perimeter and gain access to local network resources. Source.
So, what kind of training can you do to help your staff avoid threats?
Identification training: Provide staff members with the knowledge and tools they need to recognize potential threats. This includes identifying suspicious emails, websites, or software, and understanding the dangers of clicking on unverified links or downloading unknown attachments, and also knowing how to handle and report a suspected threat when one arises.
Understanding human attack vendors: Cybercriminals often target individuals within an organization, exploiting common human weaknesses such as lack of awareness or curiosity. By understanding how these attacks work, employees can be better equipped to avoid falling victim to them.
Preventing attacks: Ultimately, the goal of cyber security training is to prevent attacks. By training staff on how to recognize and respond to potential threats, businesses can drastically reduce their risk of a successful ransomware attack. This not only helps the company’s data but also its reputation and financial well-being.
Also, it is important to remember that cybersecurity training should not be a one-time event. Cyber threats are constantly evolving, so regular training is necessary to ensure that staff members are aware of the latest threats and the best practices for dealing with them.
Protecting Your NAS Data From Threats
Ransomware is an ever evolving threat in our digital world and NAS devices are no exception. With the rising popularity of NAS devices among businesses, cybercriminals have been targeting NAS devices with high profile ransomware campaigns.
Having a comprehensive understanding of the basics of ransomware to recognize why NAS devices are attractive targets is the first step toward protecting your NAS devices from these attacks. By keeping systems and applications updated, enforcing robust credentials, limiting access, employing proactive network security measures, and backing up data, you can create a strong defense line against ransomware attacks.
Additionally, investing in regular cybersecurity training for all users can significantly decrease the risk of an attack being successful due to human error. Remember, cybersecurity is not a one-time effort but a continuous process of learning, adapting, and implementing best practices. Stay informed about the latest NAS ransomware types and tactics, maintain regular audits of your NAS devices, and continuously reevaluate and improve your security measures.
Every step you take towards better security not only protects your NAS data, but sends a strong message to cybercriminals and contributes towards a safer digital ecosystem for all.
A simple question inspired this blog: At what size of RAID should you have a two-drive tolerance instead of one for your NAS device? The answer isn’t complex per se, but there were enough “if/thens” that we thought it warranted a bit more explanation.
So today, I’m explaining everything you need to know to choose the right RAID level for your needs, including their benefits, drawbacks, and different use cases.
Refresher: What’s NAS? What Is RAID?
NAS stands for network attached storage. It is an excellent solution for organizations and users that require shared access to large amounts of data. NAS provides cost-effective, centralized storage that can be accessed by multiple users, from different locations, simultaneously. However, as the amount of data stored on NAS devices grows, the risk of data loss also increases.
This is where RAID levels come into play. RAID stands for redundant array of independent disks (or “inexpensive disks” depending on who you ask), and it’s crucial for NAS users to understand the different RAID levels so they can effectively protect data while ensuring optimal performance of their NAS system.
Both NAS devices and RAID are disk arrays. That is, they are a set of several hard disk drives (HDDs) and/or solid state drives (SSDs) that store large amounts of data, orchestrating the drives to work as one unit. The biggest difference is that NAS is configured to work over your network. That means that it’s easy to configure your NAS device to support RAID levels—you’re combining the RAID’s data storage strategy and the NAS’s user-friendly network capabilities to get the best of both worlds.
What Is RAID Storage?
RAID was first introduced by researchers at the University of California, Berkeley in the late 1980s. The original paper, “A Case for Redundant Arrays of Inexpensive Disks (RAID)”, was authored by David Patterson, Garth A. Gibson, and Randy Katz, where they introduced the concept of combining multiple smaller disks into a single larger disk array for improved performance and data redundancy.
They also argued that the top-performing mainframe disk drives of the time could be beaten on performance by an array of the inexpensive drives. Since then, RAID has become a widely used data storage technology in the data storage industry, and many different levels of RAID levels evolved over time.
What Are the Different Types of RAID Storage Techniques?
Before we learn more about the different types of RAID levels, it’s important to understand the different types of RAID storage techniques so that you will have a better understanding of how RAID levels work. There are essentially three types of RAID storage techniques—striping, mirroring, and parity.
Striping
Striping distributes your data over multiple drives. If you use a NAS device, striping spreads the blocks that comprise your files across the available hard drives simultaneously. This allows you to create one large drive, giving you faster read and write access since data can be stored and retrieved concurrently from multiple disks. However, striping doesn’t provide any redundancy whatsoever. If a single drive fails in the storage array, all data on the device can be lost. Striping is usually used in combination with other techniques, as we’ll explore below.
Striping
Mirroring
As the name suggests, mirroring makes a copy of your data. Data is written simultaneously to two disks, thereby providing redundancy by having two copies of the data. Even if one disk fails, your data can still be accessed from the other disk.
Mirroring
There’s also a performance benefit here for reading data—you can request blocks concurrently from the drives (e.g. you can request block 1 from HDD1 at the same time as block 2 from HDD2). The disadvantage is that mirroring requires twice as many disks for the same total storage capacity.
Parity
Parity is all about error detection and correction. The system creates an error correction code (ECC) and stores the code along with the data on the disk. This code allows the RAID controller to detect and correct errors that may occur during data transmission or storage, thereby reducing the risk of data corruption or data loss due to disk failure. If a drive fails, you can install a new drive and the NAS device will restore your files based on the previously created ECC.
Parity
What Is RAID Fault Tolerance?
In addition to the different RAID storage techniques mentioned above, the other essential factor to consider before choosing a RAID level is RAID fault tolerance.” RAID fault tolerance refers to the ability of a RAID configuration to continue functioning even in the event of a hard disk failure.
In other words, fault tolerance gives you an idea on how many drives you can afford to lose in a RAID level configuration, but still continue to access or re-create the data. Different RAID levels offer varying degrees of fault tolerance and redundancy, and it’s essential to understand the trade-offs in storage capacity, performance, and cost as we’ll cover next.
What Are the Different RAID Levels?
Now that you understand the basics of RAID storage, let’s take a look at the different RAID level configurations for NAS devices, including their benefits, use cases, and degree of fault tolerance.
RAID levels are standardized by the Storage Networking Industry Association (SNIA) and are assigned a number based on how they affect data storage and redundancy. While RAID levels evolved over time, the standard RAID levels available today are RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10. In addition to RAID configurations, non-RAID drive architectures also exist like JBOD, which we’ll explain first.
JBOD: Simple Arrangement, Data Written Across All Drives
JBOD, also referred to as “Just a Bunch of Disks” or “Just a Bunch of Drives”, is a storage configuration where multiple drives are combined as one logical volume. In JBOD, data is written in a sequential way, across all drives without any RAID configuration. This approach allows for flexible and efficient storage utilization, but it does not provide any data redundancy or fault tolerance.
JBOD: Just a bunch of disks.
JBOD has no fault tolerance to speak of. On the plus side, it’s the simplest storage arrangement, and all disks are available for use. But, there’s no data redundancy and no performance improvements.
RAID 0: Striping, Data Evenly Distributed Over All Disks
RAID 0, also referred to as a “stripe set” or “striped volume”, stores the data evenly across all disks. Blocks of data are written to each disk in the array in turn, resulting in faster read and write speeds. However, RAID 0 doesn’t provide fault tolerance or redundancy. The failure of one drive can cause the entire storage array to fail, resulting in total loss of data.
RAID 0 also has no fault tolerance. There are some pros: it’s easy to implement, you get faster read/write speeds, and it’s cost effective. But there’s no data redundancy and an increased risk of data loss.
RAID 0: Data evenly distributed across two drives.
Raid 0: The Math
We can do a quick calculation to illustrate how RAID 0, in fact, increases the chance of losing data. To keep the math easy, we’ll assume an annual failure rate (AFR) of 1%. This means that, out of a sample of 100 drives, we’d expect one of them to fail in the next year; that is, the probability of a given drive failing in the next year is 0.01.
Now, the chance of the entire RAID array failing–its AFR–is the chance that any of the disks fail. The way to calculate this is to recognize that the probability of the array surviving the year is simply the product of the probability of each drive surviving the year. Note: we’ll be rounding all results in this article to two significant figures.
Multiply the possibility of one drive failing by the number of drives you have. In this example, there are two.
0.99 x 0.99 = 0.98
Subtract that result from one to calculate the percentage. So, the AFR is:
1 – 0.98 = 0.02, or 2%
So the two-drive RAID array is twice as likely to fail as a single disk.
RAID 1: Mirroring, Exact Copy of Data on Two or More Disks
RAID 1 uses disk mirroring to create an exact copy of a set of data on two or more disks to protect data from disk failure. The data is written to two or more disks simultaneously, resulting in disks that are identical copies of each other. If one disk fails, the data is still available on the other disk(s). The array can be repaired by installing a replacement disk and copying all the data from the remaining drive to the replacement. However, there is still a small chance that the remaining disk will fail before the copy is complete.
RAID 1 has a fault tolerance of one drive. Advantages include data redundancy and improved read performance. Disadvantages include reduced storage capacity compared to disk potential. It also requires twice as many disks as RAID 0.
RAID 1: Exact copy of data on two or more disks.
RAID 1: The Math
To calculate the AFR for a RAID 1 array, we need to take into account the time needed to repair the array—that is, to copy all of the data from the remaining good drive to the replacement. This can vary widely depending on the drive capacity, write speed, and whether the array is in use while it is being repaired.
For simplicity, let’s assume that it takes a day to repair the array, leaving you with a single drive. The chance that the remaining good drive will fail during that day is simply (1/365) x AFR:
(1/365) x 0.01 = 0.000027
Now, the probability that the entire array will fail is the probability that one drive will fail and also the remaining good drive fail during that one-day repair period:
0.01 x 0.000027 = 0.00000027
Since there are two drives, and so two possible ways for this to happen, we need to combine the probabilities as we did in the RAID 0 case:
1 – (1 – 0.00000027) x 2 = 0.00000055 = 0.000055%
That’s a tiny fraction of the AFR for a single disk—out of two million RAID arrays, we’d expect just one of them to fail over the course of a year, as opposed to 20,000 out of a population of two million single disks.
When AFRs are this small, we often flip the numbers around and talk about reliability in terms of “number of nines.” Reliability is the probability that a device will survive the year. Then, we just count the nines after the decimal point, disregarding the remaining figures. Our single drive has reliability of 0.99, or two nines, and the RAID 0 array has just a single nine with its reliability of 0.98.
The reliability of this two-drive RAID 1 array, given our assumption that it will take a day to repair the array, is:
1 – 0.00000055 = 0.99999945
Counting the nines, we’d also call this six nines.
RAID 5: Striping and Parity With Error Correction
RAID 5 uses a combination of disk striping and parity to distribute data evenly across multiple disks, along with creating an error correction code. Parity, the error correction information, is calculated and stored in one block per stripe set. This way, even if there is a disk failure, the data can be reconstructed using error correction.
RAID 5 also has a fault tolerance of one drive. On the plus side, you get data redundancy and improved performance. It’s a cost-effective solution for those who need redundancy and performance. On the minus side, you only get limited fault tolerance: RAID 5 can only tolerate one disk failure. If two disks fail, data will be lost.
RAID 5: Striping and parity distributed across disks.
RAID 5: The Math
Let’s do the math. The array fails when one disk fails, and any of the remaining disks fail during the repair period. A RAID 5 array requires a minimum of three disks. We’ll use the same numbers for AFR and repair time as we did previously.
We’ve already calculated the probability that either disk fails during the repair time as 0.000027.
And, given that there are three ways that this can happen, the AFR for the three-drive RAID array is:
1 – (1 – 0.000027)3 = 0.000082 = 0.0082%
To calculate the durability, we’d perform the same operation as previous sections (1 – AFR), which gives us four nines. That’s much better durability than a single drive, but much worse than a two-drive RAID 1 array. We’d expect 164 of two million three-drive RAID 5 arrays to fail. The tradeoff is in cost-efficiency—67% of the three-drive RAID 5 array’s disk space is available for data, compared with just 50% of the RAID 1 array’s disk space.
Increasing the number of drives to four increases the available space to 75%, but, since the array is now vulnerable to any of the three remaining drives failing, it also increases the AFR, to 0.033%, or just one nine.
RAID 6: Striping and Dual Parity With Error Correction
RAID 6 uses disk striping with dual parity. As with RAID 5, blocks of data are written to each disk in turn, but RAID 6 includes two parity blocks in each stripe set. This provides additional data protection compared to RAID 5, and a RAID 6 array can withstand two drive failures and continue to function.
With RAID 6, you get a fault tolerance of two drives. Advantages include higher data protection and improved performance. Disadvantages include reduced write speed. Due to dual parity, write transactions are slow. It also takes longer to repair the array because of its complex structure.
RAID 6: Striping and dual parity with error correction.
RAID 6: The Math
The calculation for a four-drive RAID 6 array is similar to the four-drive RAID 5 case, but this time, we can calculate the probability that any two of the remaining three drives fail during the repair. First, the probability that a given pair of drives fail is:
(1/365) x (1/365) = 0.0000075
There are three ways this can happen, so the probability that any two drives fail is:
1 – (1 – 0.0000075)3 = 0.000022
So the probability of a particular drive failing, then a further two of the remaining three failing during the repair is:
0.01 * 0.000022 = 0.00000022
There are four ways that this can happen, so the AFR for a four-drive RAID array is therefore:
1 – (1 – 0.000000075)4 = 0.0000009, or 0.00009%
Subtracting our result from one, we calculate six nines of durability. We’d expect just two drives out of approximately two million to fail within a year. It’s not surprising that the AFR is similar to RAID 1, since, with a four-drive RAID 6 array, 50% of the storage is available for data.
As with RAID 5, we can increase the number of drives in the array, with a corresponding increase in the AFR. A five-drive RAID 6 array allows use of 60% of the storage, with an AFR of 0.00011%, or five nines; two of our approximately two million drives would fail.
RAID 1+0: Striping and Mirroring for Protection and Performance
RAID 1+0, also known as RAID 10, is a combination of RAID 0 and RAID 1, in which it combines both striping and mirroring to provide enhanced data protection and improved performance. In RAID 1+0, data is striped across multiple mirrored pairs of disks. This means that if one disk fails, the other disk on the mirrored pair can still provide access to the data.
RAID 1+0 requires a minimum of four disks, of which two will be used for striping and two for mirroring, allowing you to combine the speed of RAID 0 with the dependable data protection of RAID 1. It can tolerate multiple disk failures as long as they are not in the same mirrored pair of disks.
With RAID 1+0, you get a fault tolerance of one drive per mirrored set. This gives you high data protection and improved performance over RAID 1 or RAID 5. However, it comes at a higher cost as it requires more disks for data redundancy. Your storage capacity is also reduced (only 50% of the total disk space is usable).
RAID 10: Striping and mirroring for protection and performance.
The below table shows a quick summary of the different RAID levels, their storage methods, and their fault tolerance levels.

How Many Parity Disks Do I Need?
We’ve limited ourselves to the standard RAID levels in this article. It’s not uncommon for NAS vendors to offer proprietary RAID configurations offering features such as the ability to combine different sizes of disks into a single array, but the calculation usually comes down to fault tolerance, which is the same as the number of parity drives in the array.
The common case of a four-drive NAS device, assuming a per-drive AFR of 1% and a repair time of one day:
RAID Level
Storage Method
Fault Tolerance Level
Notes
RAID 2
Bit-level striping, variable number of dedicated parity disks
Variable
More complex than RAID 5 and 6 with negligible gains.
RAID 3
Byte-level striping, dedicated parity drive
One drive
Again, more complex than RAID 5 and 6 with no real benefit.
RAID 4
Block-level striping, dedicated parity drive
One drive
The dedicated parity drive is a bottleneck for writing data, and there is no benefit over RAID 5.
RAID 5, dedicating a single disk to parity, is a good compromise between space efficiency and reliability. Its AFR of 0.033% equates to an approximately one in 3000 chance of failure per year. If you prefer longer odds, then you can move to mirroring or two parity drives, giving you odds of between one in one million and one in three million.
A note on our assumptions: In our calculations, we assume that it will take one day to repair the array in case of disk failure. So, as soon as the disk fails, the clock is ticking! If you have to go buy a disk, or wait for an online order to arrive, that repair time increases, with a corresponding increase in the chances of another disk failing during the repair. A common approach is to buy a NAS device that has space for a “hot spare”, so that the replacement drive is always ready for action. If the NAS device detects a drive failure, it can immediately bring the hot spare online and start the repair process, minimizing the chances of a second, catastrophic, failure.
Even the Highest RAID Level Still Leaves You Vulnerable
Like we said, answering the question “What RAID level do you need?” isn’t super complex, but there are a lot of if/thens. Now, you should have a good understanding of the different RAID levels, the fault tolerance they provide, and their pros and cons. But, even with the highest RAID level, your data could still be vulnerable.
While different RAID levels offer different levels of data redundancy, they are not enough to provide complete data protection for NAS devices. RAID provides protection against physical disk failures by storing multiple copies of NAS data on different disks to achieve fault tolerance objectives. However, it does not protect against the broader range of events that could result in data loss, including natural disasters, theft, or ransomware attacks. Neither does RAID protect against user error. If you inadvertently delete an important file from your NAS device, it’s gone from that array, no matter how parity disks you have.
Of course, that assumes you have no backup files. To ensure complete NAS data protection, it’s important to implement additional measures for a complete backup strategy, such as off-site cloud backup—not that we’re biased or anything. Cloud storage solutions are an effective tool to protect your NAS data with a secure, off-site cloud backup, ensuring your data is secured against various data loss threats or other events that could affect the physical location of the NAS.
At the end of the day, taking a multi-layered approach is the safest way to protect your data. RAID is an important component to achieve data redundancy, but additional measures should also be taken for increased cyber resilience.
We’d love to hear from you about any additional measures you’re taking to protect your NAS data besides RAID. Share your thoughts and experiences in the comments below.
With recent reports showing the global NAS market size is projected to grow from $26 billion to $82.9 billion in 2030, it’s clear that NAS isn’t going anywhere. So, let’s talk about how to choose an enterprise-level NAS solution.
What Is an Enterprise NAS?
Enterprise NAS is a large-scale data storage system that is connected to a local network to provide data storage and access to the organization. It’s designed for large-scale business environments that require high-capacity storage, superior performance, and advanced data management capabilities.
Compared with home-use NAS devices, enterprise NAS devices often come with superior hardware specifications, including powerful processors, large amounts of memory (RAM), and numerous drive bays to accommodate vast amounts of data.
How Do Enterprises Use NAS Devices?
Enterprises use NAS devices for a wide range of use cases and applications:
File storage and sharing: NAS devices provide a centralized platform for storing and sharing files across a network. This fosters collaboration, as employees can easily access shared files regardless of their physical location.
Data protection: With built-in redundancy features, NAS devices offer robust data protection. This ensures data remains safe and accessible even in the event of a disk failure.
Disaster recovery: Snapshot and replication features allow for quick restoration of data minimizing downtime and data loss from hardware failures, cyberattacks, or natural disasters. However, it’s important to note that NAS devices alone don’t provide this protection—they’re subject to the same vulnerabilities as all on-premises devices. Rather, this benefit comes from a NAS setup that tiers to the cloud.
Hosting business applications: Businesses can also use NAS devices to host business applications. Much the same as how you would use a server, since these devices can handle high volumes of data traffic and support multiple connections, they are well suited for running enterprise-level applications that require high availability and performance.
Running virtual machines (VMs): Virtualization software providers, like VMware, support running their products on NAS. With proper configuration, including potentially adding RAM to your device, you can easily spin up virtual machines using NAS.
Using NAS as a file server: NAS devices can function as dedicated file servers, offering high-performance, stable environments, which are useful for businesses with large user bases requiring concurrent access to shared files.
Archiving: Long-term storage and archiving is another key application of NAS devices in the enterprise. There are benefits to having archival data on-premises. It can reduce recovery times in case you need to restore from backups.
Enterprise NAS vs. Server Area Networks (SAN)
As you’re choosing how to create an enterprise-level storage system, it’s important to know the differences between NAS and SAN. The short answer: From the perspective of the user, there’s not much difference. From the perspective of the person managing the system, SAN setups are more complex and have more customization options, particularly in your network connections.
However, NAS companies have done an excellent job of adding functionality to NAS devices, making those features easily manageable. Since they’re less complex, they may be easier for your internal IT team to manage—and that can translate to OpEx savings and more time for your IT team to stay on top of challenges in an ever-changing tech landscape.
What Is the Difference Between Entry-Level, Mid-Market, and Enterprise NAS Devices?
NAS devices can be grouped into three major categories based on factors such as storage capacity, performance, and scalability. The following table provides a side-by-side comparison of the key features and differences between entry-level, mid-market, and enterprise NAS devices.
Feature
Entry-Level NAS
Mid-Market NAS
Enterprise NAS
Storage Capacity
Up to a few terabytes.
Can range from a few terabytes to tens of terabytes.
Usually hundreds of terabytes or more, scalable to meet enterprise needs.
Performance
Adequate for home use and basic file sharing.
Enhanced performance for small to medium businesses with higher data traffic.
High-performance systems designed to handle heavy workloads and concurrent access.
Reliability & Redundancy
Basic redundancy usually with RAID 1 or RAID 5 options.
More advanced redundancy options, including multiple RAID configurations.
Highly reliable with advanced redundancy features (RAID, replication, etc.).
Scalability
Limited scalability.
Moderate scalability, depending on model.
Highly scalable with clustering options.
Advanced Features
Basic features like media streaming, remote access, and basic data redundancy.
More advanced features like virtualization, data encryption, access control, and snapshot capability.
Enterprise-grade features like high-speed data transfers, advanced backup and disaster recovery options, deduplication, encryption, and virtualization support.
How Do I Choose an Enterprise NAS Device?
Now that you understand the difference between the different types of NAS devices and their respective features, it’s crucial to understand your specific business needs before choosing an enterprise NAS device. There are several aspects to consider, so let’s take them one by one.
1. Storage Capacity
One of the first things to consider is the amount of storage your enterprise requires. This isn’t just about your current needs, but also about the projected growth of your data over time. In a NAS system, storage is defined by the number of drives, the total amount of shared volume they create, and their striping scheme. A striping scheme defines where data is stored and what kinds of redundancies it has, and is also known as RAID levels that are usually defined like so: RAID 0, 1 5, 6, etc.
There are a few ways to add storage to a NAS device.
You can add drives to your NAS unit if you originally provisioned one with extra bays. This is most applicable to entry-level units.
You can purchase another NAS device and network it with your first device. On the enterprise level, you’ll likely have a more complex architecture of connected NAS devices acting as clusters or nodes on your network.
Finally, cloud-connected NAS devices mean that you can provision both primary and backup data to the cloud, so your setup is infinitely scalable. This means you can also nimbly add more storage on a short time frame—no need to wait for hardware upgrades (though you may still want to make upgrades in the longer term).
2. Data Access Speeds
The speed at which data can be accessed from your NAS device is another crucial factor. NAS devices are built to be directly connected to your local area network (LAN) and usually require a direct ethernet connection. An entry-level NAS system will have a gigabit ethernet connection (1GigE), and is suitable for entry-level or home NAS users.
But for enterprises that want to provide frequent and intensive data access to a large number of users, NAS vendors offer higher capacity ethernet connections on their systems. Some vendors offer 2.5 Gb/s or 5 Gb/s connections on their systems, but they usually require that you get a compatible network switch, USB adapters, or expansion cards. Still other NAS systems provide the option of Thunderbolt connections in addition to ethernet connections to provide higher bandwidth—up to 40GigE—and are good for systems that need to edit large files directly on the NAS.
3. Scalability
As your business grows, your data needs will likely increase. Therefore, it’s essential that your NAS device has the ability to grow with your business. You may not know exactly how much data you’ll need in a year or five, but you can certainly make an estimate based on your product roadmap, current rate of growth, and so on. And, we put together this handy NAS Buyer’s Guide so you can compare that potential growth to existing NAS features.
With any good backup strategy, you’ll want to set up recurring and automatic backups of all your systems. Also, in complex environments like a business, backups are just as much about data management—that is, knowing where all your data is stored (the shared file system vs. employee workstations vs. the cloud) and how to back it up effectively.
Enterprise NAS devices provide advanced data protection and backup features to protect NAS data against data loss and enhance accessibility. These include advanced RAID configurations (i.e. on what server and how redundant your data storage is), automated backup features, cloud storage integrations, enterprise grade encryption features, advanced backup and disaster recovery options, data deduplication, encryption, and virtualization support, etc.
Other features to look for can include snapshot technology, which allows capturing the state of the system at different points in time, and replication features which enable copying of data from one NAS device to another for redundancy.
5. Evaluating Total Cost of Ownership
When evaluating an investment in an enterprise NAS device, it’s important to not limit your focus on the initial purchase price of the NAS device itself. Keep in mind that with a NAS device, you’ll need to purchase hard drives (HDDs) or solid-state drives (SSDs) (and possibly other devices) to complete your setup.
Depending on the kind of data durability you want to create, the storage hardware cost can add up if you’re aiming for high capacity storage with advanced RAID configurations. Also, make sure to take into account energy consumption, software licenses, labor and IT costs, and maintenance costs.
6. Vendor Support and Warranty
One of the often ignored and underestimated parts of selecting an enterprise NAS device is the support and warranty provided by the NAS vendors. Enterprise NAS devices are complex pieces of technology. NAS devices, in general, are designed to be user-friendly, but once you’re networking NAS devices on the enterprise level, things get more complex.
When you encounter an issue, addressing the challenges as quickly as possible can mean the difference between prolonged downtime and quick resolution. Of course, this means having in-house IT support, but it’s also absolutely critical to choose an enterprise NAS vendor that provides robust support and a good warranty to ensure the resilience and longevity of your enterprise NAS solution.
Level Up: Connect Your Enterprise NAS to the Cloud
Okay, so you’ve chosen your enterprise NAS and devised your on-site, connected NAS solution. In industry parlance, what you’ve essentially done is to create a private cloud: storage dedicated solely to your organization, but accessible from anywhere. But, if you only have on-site storage, your data is vulnerable to theft, natural disasters, fire, and so on; and, as we mentioned above, you always want to have multiple copies of your data with at least one copy stored off-site.
The easiest way to achieve this is to connect your NAS to a public cloud service provider (CSP) like Backblaze. Make sure that you take into account the location of the CSP’s data centers to ensure that you have adequate geographic separation between your data. And, once connected to a CSP, you can take advantage of services like cloud replication to create yet another redundant copy of your data automatically.
Beyond backups, data storage on your NAS vs. in the cloud can have performance (speed) differences. This has implications on both your internal workflows and your external workflows. Take the use case of a media and entertainment company: when you’re editing files, you’re typically working with large, raw files that take time to transmit. That means that on-site storage can be faster for your team. But, teams have become more remote, and you might be using freelancers.
The great news is that most NAS devices have data management and syncing features, as noted above. A NAS hybrid cloud setup lets your employees or freelancers access remotely. They can access data via cloud storage, and your NAS client takes care of making sure all versions are up-to-date.
Once you have your business’ hybrid cloud setup, then you’ve opened up several opportunities to enhance how you store, manage, and use your data.
Store your data closer to delivery endpoints for faster speeds. If you’re creating, editing, or delivering large files like you would in the media and entertainment industry, the physical location of your data makes a difference to how fast you can deliver it to the end user. Depending on where your endpoints are located and what region you choose, using cloud storage as an active archive allows you to store data closer to delivery endpoints for fast access.
Integrate your NAS device with software as a service (SaaS) tools. In our SaaS landscape, all of our programs are internet-connected, and all of them need to be connected to storage. Many of these tools have their own clouds (like Google Drive or Adobe Creative Cloud) that you can bypass by connecting your own cloud storage account. Your NAS client then has excellent sync tools to keep your files updated as necessary, and, since that file is on your network instead of the tool’s cloud, it will be protected by your backup rules.
Actively strengthen your backups. We’ve talked about the need for geographic separation, and storing in the cloud is the easiest way to do this. (People used to ship tape backups back in the distant past of the 1990s and early 2000s.) You can also set up different rules for your different files. Your primary storage obviously needs to be modifiable, but you can use tools like Object Lock to set immutable rules on your backups as well.
Scale your storage flexibly. One of the biggest challenges of on-site storage is that adding more storage means buying more drives—it’s not an instant solution—and you’re more vulnerable to fluctuations in the supply chain. (Remember the Thailand Drive Crisis?) While you want to plan for future storage needs, cloud storage lets you add more storage immediately should you have unexpected needs.
Sum Up and Get Started
As you can see, having a clear understanding of your business needs is crucial before you build your storage strategy. Choosing an enterprise NAS is not only about getting a device that works now, but one that will continue to serve your business efficiently as your organization grows and evolves. A well thought-out enterprise NAS selection can boost your data management, provide robust data protection, and support your business’s growth goals.

In today’s fast-paced media landscape, efficient collaboration is essential for success. With teams managing large files between geographically dispersed team members on tight deadlines, the need for a robust, flexible storage solution has never been greater. Hybrid cloud storage addresses this need by combining the power of on-premises solutions, like network attached storage (NAS) devices, with cloud storage, creating an ideal setup for enhanced productivity and seamless collaboration.
In this post, I’ll walk you through some approaches for optimizing media workflows using hybrid cloud storage. You’ll learn how to unlock fast local storage, easy file sharing and collaboration, and enhanced data protection, which are all essential components for success in the media and entertainment industry.
Plus, we’ll share specific media workflows for different types of collaboration scenarios and practical steps you can take to get started with your hybrid cloud approach today using Synology NAS and Backblaze B2 Cloud Storage as an example.
Common Challenges for Media Teams
Before we explore a hybrid cloud approach that combines NAS devices with cloud storage, let’s first take a look at some of the common challenges media teams face, including:
Data storage and accessibility.
File sharing and collaboration.
Security and data protection.
Data Storage and Accessibility Challenges
It’s no secret that recent data growth has been exponential. This is no different for media files. Cameras are creating larger and higher-quality files. There are more projects to shoot and edit. And editors and team members require immediate access to those files due to the high demand for fresh content.
File Sharing and Collaboration Challenges
Back in 2020, everyone was forced to go remote and the workforce changed. Now you can hire freelancers and vendors from around the world. This means you have to share assets with external contributors, and, in the past, this used to exclusively mean shipping hard drives to said vendors (and sometimes, it can still be necessary). Different contractors, freelancers, and consultants may use different tools and different processes.
Security and Data Protection Challenges
Data security poses unique challenges for media teams due to the industry’s specific requirements including managing large files, storing data on physical devices, and working with remote teams and external stakeholders. The need to protect sensitive information and intellectual property from data breaches, accidental deletions, and device failures adds complexity to data protection initiatives.
How Does Hybrid Cloud Help Media Teams Solve These Challenges?
As a quick reminder, the hybrid cloud refers to a computing environment that combines the use of both private cloud and public cloud resources to achieve the benefits of each platform.
A private cloud is a dedicated and secure cloud infrastructure designed exclusively for a single tenant or organization. It offers a wide range of benefits to users. With NAS devices, organizations can enjoy centralized storage, ensuring all files are accessible in one location. Additionally, it offers fast local access to files that helps streamline workflows and productivity.
The public cloud, on the other hand, is a shared cloud infrastructure provided by cloud storage companies like Backblaze. With public cloud, organizations can scale their infrastructure up or down as needed without the up-front capital costs associated with traditional on-premises infrastructure.
By combining cloud storage with NAS, media teams can create a hybrid cloud solution that offers the best of both worlds. Private local storage on NAS offers fast access to large files while the public cloud securely stores those files in remote servers and keeps them accessible at a reasonable price.
How To Get Started With A Hybrid Cloud Approach
If you’d like to get started with a hybrid cloud approach, using NAS on-premises is an easy entry point. Here are a few tips to help you choose the right NAS device for your data storage and collaboration needs.
Storage Requirements: Begin by assessing your data volume and growth rate to determine how much storage capacity you’ll need. This will help you decide the number of drives required to support your data growth.
Compute Power: Evaluate the NAS device’s processor, controller, and memory to ensure it can handle the workloads and deliver the performance you need for running applications and accessing and sharing files.
Network Infrastructure: Consider the network bandwidth, speed, and port support offered by the NAS device. A device with faster network connectivity will improve data transfer rates, while multiple ports can facilitate the connection of additional devices.
Data Collaboration: Determine your requirements for remote access, sync direction, and security needs. Look for a NAS device that provides secure remote access options, and supports the desired sync direction (one-way or two-way) while offering data protection features such as encryption, user authentication, and access controls.
By carefully reviewing these factors, you can choose a NAS device that meets your storage, performance, network, and security needs. If you’d like additional help choosing the right NAS device, download our complete NAS Buyer’s Guide.
Real-World Examples: Using Synology NAS + Backblaze B2
Let’s explore a hybrid cloud use case. To discuss specific media workflows for different types of collaboration scenarios, we’re going to use Synology NAS as the private cloud and Backblaze B2 Cloud Storage as the public cloud as examples in the rest of this article.
Scenario 1: Working With Distributed Teams Across Locations
In the first scenario, let’s assume your organization has two different locations with your teams working from both locations. Your video editors work in one office, while a separate editorial team responsible for final reviews operates from the second location.
To facilitate seamless collaboration, you can install a Synology NAS device at both locations and connect them to Backblaze B2 using Cloud Sync.
Here’s a video guide that demonstrates how to synchronize Synology NAS to Backblaze B2 using cloud sync.
This hybrid cloud setup allows for fast local access, easy file sharing, and real-time synchronization between the two locations, ensuring that any changes made at one site are automatically updated in the cloud and mirrored at the other site.
Scenario 2: Working With Distributed Teams
In this second scenario, you have teams working on your projects from different regions, let’s say the U.S. and Europe. Downloading files from different parts of the world can be time-consuming, causing delays and impacting productivity. To solve this, you can use Backblaze B2 Cloud Replication. This allows you to replicate your data automatically from your source bucket (U.S. West) to a destination bucket (EU Central).
Source files can be uploaded into B2 Bucket on the U.S. West region. These files are then replicated to the EU Central region so you can move data closer to your team in Europe for faster access. Vendors and teams in Europe can configure their Synology NAS devices with Cloud Sync to automatically sync with the replicated files in the EU Central data center.
Scenario 3: Working With Freelancers
In both scenarios discussed so far, file exchanges can occur between different companies or within the same company across various regions of the world. However, not everyone has access to these resources. Freelancers make up a huge part of the media and entertainment workforce, and not every one of them has a Synology NAS device.
But that’s not a problem!
In this case, you can still use a Synology NAS to upload your project files and sync them with your Backblaze B2 Bucket. Instead of syncing to another NAS or replicating to a different region, freelancers can access the files in your Backblaze B2 Bucket using third-party tools like Cyberduck.
This approach allows anyone with an internet connection and the appropriate access keys to access the required files instantly without needing to have a NAS device.
Scenario 4: Working With Vendors
In this final scenario, which is similar to the first one, you collaborate with another company or vendor located elsewhere instead of working with your internal team. Both parties can install their own Synology NAS device at their respective locations, ensuring centralized access, fast local access, and easy file sharing and collaboration.
The two NAS devices are then connected to a Backblaze B2 Bucket using Cloud Sync, allowing for seamless synchronization of files and data between the two companies.
Whenever changes are made to files by one company, the updated files are automatically synced to Backblaze B2 and subsequently to the other company’s Synology NAS device. This real-time synchronization ensures that both companies have access to the latest versions of the files, allowing for increased efficiency and collaboration.
Making Hybrid Cloud Work for Your Production Team
As you can see, there are several different ways you can move your media files around and get them in the hands of the right people—be it another one of your offices, vendors, or freelancers. The four scenarios discussed here are just a few common media workflows. You may or may not have the same scenario. Regardless, a hybrid cloud approach provides you with all the tools you need to customize your workflow to best suit your media collaboration needs.
In addition to Synology NAS, Backblaze B2 Cloud Storage integrates seamlessly with other NAS devices such as Asustor, Ctera, Dell Isilon, iOsafe, Morro Data, OWC JellyFish, Panzura, QNAP, TrueNAS, and more. Regardless of which NAS device you use, getting started with a hybrid cloud approach is simple and straightforward with Backblaze B2.
Hybrid Cloud Unlocks Collaboration and Productivity for Media Teams
Easing collaboration and boosting productivity in today’s fast-paced digital landscape is vital for media teams. By leveraging a hybrid cloud storage solution that combines the power of NAS devices with the flexibility of cloud storage, organizations can create an efficient, scalable, and secure solution for managing their media assets.
This approach not only addresses storage capacity and accessibility challenges, but also simplifies file sharing and collaboration, while ensuring data protection and security. Whether you’re working within your team from different locations, collaborating with external partners, or freelancers, a hybrid cloud solution offers a seamless, cost-effective, and high-performance solution to optimize your media workflows and enhance productivity in the ever-evolving world of media and entertainment.

Network attached storage (NAS) devices offer centralized data storage solutions, enabling users to easily protect and access their data locally. You can think of a NAS device as a powerful computer that doesn’t have a display or keyboard. NAS can function as extended hard disks, virtual file cabinets, or centralized storage systems depending on individual needs. While NAS devices provide local data protection, a hybrid setup with cloud storage offers off-site protection by storing files on geographically remote servers.
This blog is the first in a two part series that will focus on home NAS setups, exploring how two Backblazers set up their NAS devices and connected them to the cloud. We’ll aim to present actionable setup tips and explain what each of our data storage needs are so that you can create your own NAS setup strategy.
I’m Vinodh, your first user. In this post, I will walk you through how I use a Synology Single-Bay NAS device and Backblaze B2 Cloud Storage.
Why Did I Need a NAS Device At My Home?
Before I share my NAS setup, let’s take a look at some of the reasons why I needed a NAS device to begin with. Knowing that will give you a better understanding of what I’m trying to accomplish with NAS.
My work at Backblaze involves guiding customers through all things NAS and cloud storage. I use a single-bay NAS device to understand its features and performance. I also create demos, test use cases, and develop marketing materials and back them up on my NAS and in the cloud to achieve the requirements of a 3-2-1 backup strategy. That strategy recommends that you have three copies of data stored in two different locations with one copy off-site.
Additionally, I use my NAS setup to off-load the (stunning!) photos and videos from my wife’s and my iPhones to free up space and protect them safely in the cloud. Lastly, I’d also like to mention that I work remotely and collaborate with people as part of my regular work, but today we’re going to talk about how I back up my files using a hybrid cloud storage setup that combines Synology NAS and Backblaze B2. Combining NAS and cloud storage is a great backup and storage solution for both business and personal use, providing a layer of protection in the event of hardware failures, accidental deletions, natural disasters, or ransomware attacks.
Now that you understand a little bit about me and what I’m trying to accomplish with my NAS device, let’s jump into my setup.
What Do I Need From My NAS Device?
Needless to say, there are multiple ways to set up a NAS device. But, the most common setup is for backing up your local devices (computer, phones, etc.) to your NAS device. A basic setup like this, with a few computers and devices backing up to the same NAS device, protects data in that you have a second copy of your data stored locally. However, the data can still be lost if there is hardware failure, theft, fire, or any other unexpected event that poses a threat to your home. This means that your backup strategy needs something more in order to truly protect your data.
Off-site protection with cloud storage solves this problem. So, when I planned my NAS setup, I wanted to make sure I had a NAS device that integrates well with a cloud storage provider to achieve a 3-2-1 backup strategy.
Now that we’ve talked about my underlying data protection strategy, here are the devices and tools I used to create a complete 3-2-1 NAS backup setup at my home:
Devices with data:
MacBook Pro–1
iPhone–2
Storage products:
Synology Device–1
Seagate 4TB internal hard disk drive–1
Backblaze B2 Cloud Storage
Applications:
Synology Hyper Backup
Synology Photos
What Did I Want to Back Up on My NAS Device?
My MacBook Pro is where I create test use cases, demos, and all the files I need to do my job, such as blog posts, briefs, presentation decks, ebooks, battle cards, and so on. In addition to creating files, I also download webinars, infographics, industry reports, video guides, and any other information that I find useful to support our sales and marketing efforts. As I mentioned previously, I want to protect this business data both locally (for quick access) and in the cloud (for off-site protection). This way, I can not only secure the files, but also remotely collaborate with people from different locations so everyone can access, review, and edit the files simultaneously to ensure timely and consistent messaging.
Meanwhile, my wife and I each have an iPhone 12 with 128GB storage space. Clearly, a total of 256GB is not enough for us—it only takes six to nine months for us to run out of storage on our devices. Once in a while, I clean up the storage space to make sure my phone runs at optimal speed by removing any duplicate or unwanted photos or movies. However, my wife doesn’t like to delete anything as she often wants to look back and remember that one time we went to that one place with those friends. But, she has hundreds of pictures of that one place with those friends. As a result, our iPhone family usage is almost always at capacity.
Our shared storage.
As you can see, being able to off-load pictures and movies from our phones to a local device would give us quick access, protect our memories in the cloud, and free up our iPhone storage.
How I Set Up My NAS Device
To accomplish all that, I set up a Synology Single-Bay NAS Diskstation (Model: DS118) which is powered by a 64-bit quad-core processor and 1GB DDR4 memory. As we discussed above, a NAS device is basically a computer without a display and keyboard.
Unboxing my Synology NAS.
Most NAS devices are diskless, meaning we’d need to buy hard disk drives (HDD) and install them on the NAS device. Also, it is important to note that NAS devices work differently than a typical computer. A NAS device is always running even if you turn off your computer or laptop. A regular hard disk drive may not support this operating pressure. Therefore, it’s essential that we get NAS drives that are suitable for NAS devices. For my NAS device, I got a 4TB HDD from Seagate. You can look up compatible drives on Synology’s compatibility list. When you buy your NAS, the manufacturer should give you a list of which hard drives are compatible, and you can always check out Drive Stats if you want to read up on how long drives last.
A 4TB Seagate HDD.
After getting the NAS device and HDD, the next item I wanted to figure out is where to keep it. NAS devices typically plug into routers rather than desktops or laptops. With help from my internet service provider, I was able to connect all rooms in our house with an ethernet connection that’s attached to the router. For now, I set up the NAS device in my home office on a spare desk connected to the router via an RJ45 cable.

In addition to protecting data locally on the NAS device, I also use B2 Cloud Storage for off-site protection. Every NAS has its own software that helps you set up how your backups occur from your personal devices to your NAS, and that software will also have a way to back up to the cloud. On a Synology NAS, that software is called Hyper Backup, and we’ll talk a little bit more about it below.
How I Back Up My Computer to My NAS Device
The above diagram shows how I use a hybrid setup using Synology NAS and B2 Cloud Storage to protect data locally and off-site.
First, I use Synology File Station to upload critical business data to the NAS device. After I configure B2 Cloud Storage with Hyper Backup, all files uploaded to the NAS device automatically get uploaded and stored in B2 Cloud Storage.
Getting set up with B2 Cloud Storage is a simple process. Check out this video demonstration that shows how to get your NAS data to B2 Cloud Storage in 10 minutes or less.
How I Back Up iPhone Photos and Videos to My NAS Device
That takes care of our computer backups. Now on to photo storage. To off-load photos and movies and create more storage space on my phone, I installed the application “Synology Photos” on my and my wife’s iPhones. Now, whenever we take a picture or shoot a movie on our phones, the Synology Photos application automatically stores a copy of the files to the NAS device. And, the Hyper Backup application then copies those photos and movies to B2 Cloud Storage automatically.
This setup has enabled us to not worry about storage space on our phones. Even if we delete those pictures and movies, we can still access them quickly via the NAS device over our local area network (LAN). But most importantly, a copy of those memories is protected off-site in the cloud, and I can access that cloud storage copy easily from anywhere in the world.
Lessons Learned: What I’d Do Differently The Next Time
So, what can you take from my experience setting up a NAS device at home? I learned a few things along the way that you might find useful. Here is my advice if I were to do things differently the second time around:
Number of bays: I opted for a single bay NAS device for my home setup. After using the device for about three months now, I realize how much space it saved on my MacBook and iPhones. If I were to do it again, I’d choose a NAS device with four or more bays for increased storage options.
Check for Ethernet connectivity: Not all rooms in my house were wired for Ethernet connectivity, and I did not realize that until I started setting up the NAS device. I needed to get in touch with my internet service provider to provide Ethernet connectivity in all rooms—which delayed the setup by two weeks. If you’re looking to set up a NAS device at home, ensure the desired location in your home has an Ethernet connection.
Location: I initially wanted to set up my NAS device in the laundry room. However, I realized NAS devices require a space that is well ventilated with minimum exposure to heat, dust, or moisture. Therefore, I’d chosen to set up the NAS device at my office room instead. Consider factors like ventilation, accessibility, and dust exposure of the location for the longevity and performance of your NAS device.
So, whether you are a home user who wants additional storage, a small business owner who wants to create a centralized file storage system, or an IT admin for a mid-size or enterprise organization who wants to securely protect your critical business data both on-premises and off-site storage, the use of a NAS device along with cloud storage provides the protection you need to secure your data.
What’s Next: Looking Forward to Part Two
In part one of this series, we’ve learned how setting up a NAS device at home and connecting it to the cloud can effectively back up and protect critical business data and personal files while accomplishing a 3-2-1 backup strategy. Stay tuned for part two, where James Flores will share with us how he utilizes a hybrid NAS and cloud storage solution to back up, work on, and share media files with users from different locations. In the meantime, we’d love to hear about your experience setting up and using NAS devices with cloud storage. Please share your comments and thoughts below.
