What Is OpenStack?

OpenStack is a popular modular cloud operating system that handles large pools of resources. This open-source system facilitates the building and administration of both public and private clouds. The OpenStack platform’s tools, known as “projects,” manage the key cloud computing services of computation, networking, storage, identity, and imaging services. It can combine over a dozen optional projects to form unique, deployable clouds.

OpenStack consists of multiple components, such as:

• Nova (Compute)
• Neutron (Networking)
• Cinder (Block Storage)
• Glance (Image Services)
• Keystone (Identity)
• Horizon (Dashboard)

Key Benefits of OpenStack:

• Supports plugins, APIs, and third-party integrations using flexible frameworks.
•  Its broad ecosystem integrates with Red Hat, Canonical, Mirantis, and other vendors.
• Built for deep multi-tenant systems with hundreds of nodes, unparalleled scalability
• Integration of multiple hypervisors, including KVM, Xen, Hyper-V, and VMware.

Drawbacks of OpenStack:

• Requires a thorough understanding of distributed systems, virtualization, and networking.
• Particularly in production, upgrades between versions can be dangerous and disruptive, needing either complicated migration methods or downtime.

Updating software is one of the simplest and most effective ways to protect data. Unfortunately, many companies postpone or ignore this task.

In recent months, many vulnerabilities have been discovered and actively exploited in storage and backup solutions. These include tools such as Veeam Backup & Replication, MinIO, Veritas Backup Exec, Arcserve UDP, Rubrik CDM, Nakivo, QNAP QuTS Hero OS, and Pure Storage FlashArray and FlashBlade. Notably, some of the vulnerabilities in the latter were rated as a CVSS 10—requiring immediate action. Yet many companies still don’t take update warnings seriously.

Protecting sensitive and confidential data is a top priority for most CIOs. TLS encryption for internet-transmitted messages, AES-256 for data at rest, multi-factor authentication, and zero trust policies are commonly used. However, regular software updates and patching vulnerabilities are discussed far less. Experts agree that outdated software is a ticking bomb. Hackers closely monitor security patch release dates to exploit vulnerabilities in older system versions. Many users fail to follow vendor recommendations or delay updates, creating ideal attack conditions. The best-known example is WannaCry, one of the largest ransomware attacks in history. In May 2017, it infected over 300,000 computers in 99 countries, despite Microsoft releasing a patch two months earlier.

Think of software updates like car maintenance—even the best vehicle will break down without regular oil changes, and worn brake pads will eventually damage the braking system.

Similarly, not updating applications will sooner or later lead to data security breaches and reduced performance. For businesses handling sensitive customer data—such as accounting firms or financial institutions—this could mean financial losses, reputation damage, or even bankruptcy. According to research by NinjaOne, 57% of data breaches could have been prevented with regular updates.

Hitting the Last Line of Defense

While there has been progress in updating OSes and antivirus tools, storage systems and backup software are still neglected. Why? For years, backups weren’t a primary target for hackers. That changed with the rise of ransomware. IDC reports that over half of ransomware attacks target backup systems, and 60% succeed. Veeam’s 2024 Ransomware Trends Report reveals that backup repositories are attacked in 96% of cases, and cybercriminals successfully interfere in 76% of them.

Hackers know that backups are a company’s last resort. That’s why they increasingly encrypt or delete them—limiting recovery options and forcing victims to pay ransoms. Compromising backups threatens business continuity. And ransomware attacks aim not just for extortion, but also to disrupt operations and cause financial harm. Victims with compromised backups are in a weaker negotiation position. According to Sophos, companies whose backups were encrypted paid on average twice as much—a median ransom of $2.3M vs. $1M for those with intact backups.

Ransomware uses various infection vectors: phishing, remote access (RDP), and exploiting software vulnerabilities—often due to missed updates. Whether it’s a backup application or an operating system, unpatched software is a gateway. For example, Veeam CVE-2024-40711 was exploited by groups like Monti and Yanluowang. Similarly, CVE-2023-27532 was used by EstateRansomware to attack corporate environments.

Real-world impact stories stick

Example: In 2023, a mid-sized logistics firm lost all customer data after its backup server running an outdated version of Nakivo was compromised. Despite having backups, the encryption rendered recovery impossible—and the company paid over $1.5M in ransom.

Updating Backup Software = More than Just Security

The backup and disaster recovery (DR) market is evolving rapidly. Vendors regularly release new solutions or update existing ones. While security is key, it’s not the only reason to stay current. Over time, backup tools become incompatible with newer OSes, hardware, and applications.

Updated backup software often includes performance improvements—faster backups and restores, better resource usage, and support for large datasets. These enhancements reduce downtime and boost operational efficiency. Updates may also bring new data recovery features, like instant VM recovery or cross-platform restores.

While backup expenses can be high, proper updates can help reduce costs. New versions often include deduplication, compression, and other optimizations—cutting storage needs and data transfer times. This reduces storage expenses and speeds up backup processes, lightening the load on IT infrastructure.

Another major challenge for IT departments is regulatory compliance. Many industries are bound by strict data protection laws. Updated backup software often includes features that support compliance—such as data retention policies, audit logs, and reporting capabilities.

Summary Table

A Dozen Security Gaps on Average

The average enterprise storage or backup device has 14 security vulnerabilities, including three rated as high or critical. These findings come from Continuity’s State of Storage and Backup Security Report 2023, based on an analysis of 245 environments covering 8,589 devices from vendors like Dell, NetApp, Veritas, and Hitachi Vantara. Most participating organizations were in banking, but also included healthcare, telecom, and IT services.

Properly securing storage systems will soon be a core component of organizational cyber resilience strategies. Business users should not only wait for vendor updates but also adopt proactive practices, such as vulnerability scanning. That’s why interest is growing in Application Security Posture Management (ASPM) tools, which provide real-time system security monitoring. Industry regulations increasingly require automated vulnerability management. For instance, PCI DSS v4.0 mandates the use of automated vulnerability scanning tools.

In short, protecting storage and backup systems is no longer just about security—it’s also about compliance and operational efficiency.

Practical Checklist: How to Secure Your Backup Systems Today

• Audit all backup and storage software versions ✅
• Apply the latest vendor patches and security updates ✅
• Implement multi-factor authentication for backup access ✅

Complicated systems, dispersed data, information silos, and pressure to simplify. IT environments today balance the need for security with limitations of time, people, and budget. Storware Backup Appliance addresses these challenges—combining simplicity, automation, and a Zero Trust philosophy in one ready-to-use device.

Although there’s increasing talk about the need to simplify IT infrastructure, many server rooms still operate with isolated data repositories. Information is stored and managed in separate systems, which makes it difficult to share data between teams and departments within an organization. Such data dispersion limits monitoring capabilities and hinders the detection of unauthorized activities. It’s hard to protect what you can’t see and don’t have full control over. Each of these “silos” may require a separate approach to backup and Disaster Recovery, further complicating backup and data recovery processes.

Another challenge is the phenomenon of data gravity—the tendency of large data sets to attract applications, services, and additional resources. The more data accumulated in one place, the harder and more expensive it is to move. Migrating a large repository from an on-premise server room to the public cloud can take days or even weeks—or require physical transport of media. Meanwhile, new applications are being developed in the same environment that—instead of using distant services—opt for fast, local data access.

At first glance, data gravity and data dispersion seem to be opposing phenomena. In practice, however, they coexist and reinforce each other. Data remains in silos not because there’s no need for consolidation, but because its migration is often too expensive, time-consuming, or risky. In other words, it “gravitates” to a specific environment (local or cloud) and stays there.

Siloses stem from organizational, technological, and cultural divisions, while data gravity results from physical and economic processing limitations.

A real-world example: the sales and marketing department uses a CRM system in a SaaS model, with customer and campaign data located in the public cloud. In contrast, the finance department works on a local ERP system, whose data is stored on an SQL server within the company. As a result, each department operates in its own digital world, and collaboration—such as analyzing the impact of a marketing campaign on sales—becomes difficult. Migrating ERP data to the cloud involves process reengineering, significant costs, and risks.

Meanwhile, IT departments are fighting on many fronts. They handle routine, urgent tasks that—though essential—don’t add significant strategic value. They are also often responsible for the entire infrastructure: from hardware and software to configuration and user support.

Backup? It’ll Get Done After the Failure… Still Relevant Pitfalls in Data Security Thinking

A separate, but extremely important issue remains the attitude of clients themselves. Many companies still ask themselves: “Why do I need a backup if everything is working?” or “Why change systems if the current ones are functioning flawlessly?”

Costs are the most frequently cited barrier to investing in new solutions. Often, the only argument that convinces management to act is… a failure. Even in large organizations employing hundreds of people, it happens that management consciously limits IT and security spending, literally waiting for an incident to occur.

Meanwhile, regulatory pressure is growing—another regulation is set to come into force in June, expanding data protection obligations to all key companies. This will be a quick and, for many, surprising change. Despite this, the thinking that “it doesn’t concern us” still prevails. However, in today’s reality, attacks, ransomware, and incidents are not a matter of “if,” but “when.”

It’s also worth emphasizing that although the price of storage per terabyte is regularly decreasing, maintaining a consistent, secure data environment still requires investment—in people, procedures, and technologies.

Furthermore, a new, dangerous illusion has emerged: that migrating to the cloud—for example, to Microsoft 365 or Azure—relieves the organization of responsibility for backup. This is a myth. The responsibility for data protection and recovery still lies with the client. Cloud providers are responsible for the infrastructure, but not for user data.

Less Sometimes Means More

In an era of relentless cyberattacks, information security is of fundamental importance. What matters is not just the backup itself, but also the speed of reaction, reliability, readiness for change, and ease of management. Equally important are: intuitive device operation, universality, and seamless integration with both local infrastructure and the public cloud.

Our approach focuses on maximizing the simplification of IT systems. On one hand, we provide comprehensive data protection; on the other, we reduce the need to maintain separate backup systems, which are often expensive and complicated to operate. We operate on the principle that sometimes, less means more.

Storware Backup Appliance is a ready-to-use device that integrates hardware with software. Setup takes just a few minutes, and configuration and daily operation are almost maintenance-free.

The solution is based on the ZFS file system, which guarantees: data integrity, advanced compression, easy snapshot creation, and deduplication providing up to 5:1 space savings.

Backups are performed synthetically, and the appliance’s architecture allows for efficient operation even under heavy load—the only potential limitation is the client’s network infrastructure.

Storware Backup Appliance is available in three variants: SBA 1020 (maximum capacity 100 TB), SBA 2050 (up to 250 TB), and SBA 2100 (up to 500 TB). The solution not only secures data but also ensures its efficient storage. Thanks to ZFS deduplication, it’s possible to achieve up to 5:1 space savings. Backups are created synthetically, and the appliance’s architecture allows for efficient operation even under heavy load—the only potential bottleneck might be the client’s network infrastructure. Expected performance is approximately 0.5 TB per hour for a 64 KB block or 7 TB per hour for 512 KB.

Do It Yourself? Not Necessarily

An alternative to ready-made backup solutions are so-called DIY backup appliances—environments created and configured independently by IT teams, often based on existing infrastructure. This approach might seem cost-effective, but in practice, it involves greater complexity, risk, and a lack of unified technical support.

In the event of a failure, there’s no single point of contact—the responsibility for analyzing and solving the problem falls entirely on the internal team. This requires not only specialized knowledge but also the availability of people and resources 24/7.

DIY can be a good choice for organizations with large IT teams and very specific requirements. For most companies—especially those prioritizing simplicity, security, and reliable support—complete platforms provided by specialized vendors are a better solution.

Every Storware appliance is prepared individually—with a pre-installed and configured operating system, backup environment, and optimal settings. Once connected to the infrastructure, the device is ready to work—without time-consuming configurations and the risk of errors. The solution is based on enterprise-grade components: server processors, ECC memory, and disk systems optimized for intensive write operations and data deduplication. This is not just an ordinary server, but a specialized environment for data protection.

Of particular note is Paranoid Mode—a unique, proprietary RAID configuration that ensures continuous operation even in the event of a simultaneous failure of four disks. The automatic failover mechanism works automatically—without the need for administrator intervention.

Storware Backup Appliance supports a wide range of environments: virtualization (VMware, Hyper-V, KVM, Citrix, Nutanix, VergeOS), clouds (AWS, Azure, Google Cloud), container platforms (OpenShift, OpenStack), and physical infrastructure. One device provides consistent protection for all these environments—physical, virtual, and containerized—from a central point.

Security and Simplicity – Storware Backup Appliance in Practice

Modern IT environments demand solutions that are not only effective but also as user-friendly as possible and secured at multiple levels. Storware Backup Appliance demonstrates how these goals can be achieved in practice, based on the Zero Trust philosophy, intelligent automation, and a high level of component integration.

One of the key security elements in this solution is the use of the ZFS file system, which ensures not only data integrity but also effective protection. Data is stored by default on an encrypted ZFS pool, which is not automatically decrypted after a restart—physical password entry by the user is required.

The system also utilizes a TPM module, which enables automatic decryption of system partitions and those containing the library and database. This ensures the device remains fully operational, while simultaneously preventing an attacker from reading stored information if the disks are physically seized. Data access is secured in multiple layers. The end-user receives a 20-character encryption key, and for technical support, access to deeper system layers requires additional login credentials—complex passwords and 2FA authentication, available only to selected individuals within support and sales structures. The entire procedure is centrally documented, and access to the most critical components is secured with additional passwords and physical keys. This approach—though it may seem overly cautious—effectively prevents unauthorized access, even in the event of physical seizure of the device.

Storware Backup Appliance proves that a high level of security doesn’t have to mean complexity. On the contrary—properly designed mechanisms integrating encryption, access control, and automation create a system that is simultaneously easy to use, resistant to physical attacks, and compliant with best security practices.

In 2025, the International Data Corporation (IDC) projects that unstructured data will account for 80% of all data globally. Therefore, managing data load has become a big part of business-critical issues as organizations welcome petabytes of data daily.

With data volumes skyrocketing, cyber dangers growing, and regulatory pressure mounting, your backup storage option may influence how quickly (or not) you recover after a disaster. However, with so many options—file systems, object storage, and even legacy tape—how do you choose the correct one? The answer is determined by your specific backup use case rather than the technology itself.

In this article, we will review the most common backup requirements and help you determine which storage option is ideal for each. Whether you’re managing cloud-native apps or protecting archive documents, you’ll have a clear sense of what belongs where and why.

Key Backup Requirements That Shape Storage Choices

Before diving into the storage types themselves, let’s look at the real-world needs that should guide your decision:

Storing Large Volumes of Unstructured Data: This includes images, videos, IoT sensor data, logs, and social content. These data are not just large—they’re often static, accessed infrequently, and rapidly growing. You’ll want a storage option that scales effortlessly and doesn’t blow your budget.

Retaining Archived Data for Years: Sometimes, compliance or industry standards require long-term data retention. Consider financial records, legal files, or patient information. These data are rarely accessed but must be preserved securely and affordably.

Recovering from Disasters with Speed:When systems fail or ransomware strikes, time is everything. You’ll need backup storage that supports rapid restore operations and low-latency access, preferably on-site or within fast-reach infrastructure.

Operating in Hybrid and Cloud-Heavy Environments: Remote teams, distributed workloads, and cloud-native apps need accessible, API-driven, and cloud-compatible backup solutions. Scalability and flexibility matter more than physical media here.

With these use cases in mind, let’s now explore the three major backup storage types: file system, object storage, and tape.

File System: How It Works

Data in file system storage is arranged hierarchically using folders and directories. Most people use this model—files are kept on local drives or network-attached storage (NAS) devices; they have paths, names, and extensions.

Why Use a File System for Backup?

File systems are ideal for routinely accessed user-generated material or backed-up structured data. They permit rapid file- or folder-level restores and offer basic backup tools.

Best Use Cases:

• Endpoint backups (laptops, desktops)
• Departmental shares
• File servers
• Daily or weekly incremental backups
• Situations requiring fast and granular recovery

Pros:

• Easy to set up and manage
• Fast access and recovery for smaller datasets
• Familiar structure for users and admins
• Low barrier to entry

Limitations:

• Poor scalability for massive data volumes
• Not optimized for unstructured or infrequently accessed data
• Vulnerable to ransomware if not isolated or air-gapped

File systems are the go-to for daily backup requirements in smaller to mid-sized environments or as part of a multi-tiered backup plan where performance and simplicity of access are paramount.

Object Storage: How It Works

Treated as separate “objects,” object storage bundles metadata and a unique ID for each data. Unlike file systems, it is not dependent on folders or directories. Instead, items are accessed via RESTful APIs from a flat address space.

Why Use Object Storage for Backup?

Objective storage is meant for unstructured data and cloud-scale operations. It’s ideal for backup instances when remote access, long-term retention, and adaptability are critical.

Best Use Cases:

• Backing up cloud-native applications
• Storing logs, images, and sensor data
• Long-term archiving of static files
• Disaster recovery across multiple geographic regions
• Environments using automation or containerization (e.g., Kubernetes)

Pros:

• Virtually unlimited scalability
• Excellent for unstructured and infrequently accessed data
• Easy integration with cloud-based workloads
• Supports metadata-rich backups (great for indexing and search)
• Enables geo-replication and distributed redundancy

Limitations:

• Higher latency for small file access
• Requires API knowledge or management platform
• Not optimal for structured, frequently accessed transactional data

Object storage is an excellent, future-proof choice whether you are managing terabytes or petabytes of backup data—especially if it is headed for cloud or long-term storage.

Tape Backup: How It Works

Tape backup entails writing data to magnetic tape cartridges, typically using dedicated hardware like tape drives or libraries. Once written, these tapes offer physical separation from active systems by being kept offline or delivered elsewhere.

Why Use Tape for Backup?

Tape’s low cost-per-gigabyte, durability, and immutability make it useful for archive and disaster recovery even now. It’s extremely important in air-gapped settings, where ransomware danger is a concern.

Best Use Cases:

• Archiving large volumes of data for 5+ years
• Meeting compliance retention requirements
• Adding an offline layer to your disaster recovery plan
• Cold storage for infrequently accessed backups

Pros:

• High durability and longevity (often 30+ years)
• Highly cost-effective for long-term storage
• Immune to online threats (air-gapped)
• Low energy consumption compared to disk-based storage

Limitations:

• Slower restore times
• Requires physical management and logistics
• Not suitable for fast access or frequent backups
• Limited scalability without manual intervention

Tape is an excellent “last line of defense” and remains a wise choice for deep archiving, especially when combined with faster-access solutions like disk or object storage.

File System vs. Object Storage vs. Tapes: Match Your Storage to Business Strategy

Where to store backups is a question without a one-size-fits-all solution. The correct decision will depend on your company’s data types, access needs, compliance criteria, and financial situation. Many times, a hybrid strategy provides the best of both worlds. Here’s a quick bullet-point guide to help you decide:

Choose File System backup if:

• You need fast and simple access to files.
• You’re backing up structured, active data.
• Your recovery time objective (RTO) is tight.

Choose Object Storage if:

• You handle unstructured or cloud-native data.
• You require scalability and metadata-rich management.
• You need to store backups across regions or integrate with cloud tools

Choose Tape if:

• You need long-term, low-cost archival storage.
• You want offline, ransomware-resistant backups.
• You’re working under strict retention or compliance policies.

In the end, strategic backup storage is about creating resilience rather than only averting disasters. Understanding your backup goals and matching them to the strengths of every storage type helps ensure your data is ready rather than merely secure when the worst strikes.
