Hackers are targeting backup systems with ransomware! Immutable backups are the answer.

Key takeaways:
  1. Immutable backups are unalterable and indestructible copies of data that ensure business continuity and data integrity.
  2. As ransomware increasingly targets backup systems, organizations need the enhanced security of immutable backups.
  3. Traditional backups fall short against today’s cyber threats, necessitating the unalterable protection provided by data immutability.
  4. Without immutable backups, organizations risk severe data loss, highlighting the urgency of such strategies in the modern digital landscape.


Immutable backups are unalterable, indestructible copies of data that serve as a last resort for organizations seeking to restore their systems in the event of data loss. In an increasingly hostile filled with hackers and cyberattacks, where data is the lifeblood of any organization, these backups serve as an ultimate line of defense. With ransomware attacks on the rise, the importance of immutable backups, capable of withstanding any alteration attempt, has become more significant than ever before.

Ransomware Attacks are Evolving to Threaten Data Backup Systems

Ransomware attacks have significantly evolved in their strategies, posing a growing threat to all organizations. Traditionally, ransomware focused on encrypting readily accessible data, demanding a ransom to release it. However, they’re now targeting backup systems, understanding that an effective backup strategy can render ransomware ineffective.

The evolution of ransomware now sees it aiming not just at live operational data but at the backup systems designed to safeguard it. This trend, whereby the malware tries to compromise or destroy backups before launching the primary attack, leaves companies with no way to recover, significantly enhancing the attackers’ leverage.

These sophisticated attacks pose an immense risk. When backup systems are compromised, it’s not just data in danger; all operations are threatened. The immediate impact is financial, with potential revenue losses due to downtime and the costs associated with systems restoration.

In the longer term, organizations also face reputation damage. Customers and donors entrust organizations with their data, and significant data loss from a ransomware attack can break this trust, potentially leading to a loss of business or donor funding. Moreover, data forms a critical part of ongoing operations and decision-making processes. Consequently, data loss can disrupt all aspects of an organization’s success.

The Shortcomings of Conventional Backup Strategies

Conventional backup strategies often involve regular data duplication, storing data on different servers or devices, and occasionally even off-site – in the Cloud, for example. However, they still operate on the principle of accessibility, meaning the backup data can be accessed, altered, or in the worst-case scenario, completely destroyed by a ransomware attack. This vulnerability stems from the fact that many traditional backup systems allow read and write access to their stored data. While this approach was suitable in the past, the evolution of cyber threats has exposed its weakness.

In a targeted ransomware attack, cybercriminals aim to compromise not just the primary data but also the backup data. This tactic ensures that organizations can’t simply restore their systems from backups, leaving them no choice but to pay the demanded ransom. The main problem with traditional backup methods lies in their alterability. If a backup can be changed, corrupted, or deleted, it becomes useless in the face of a sophisticated ransomware attack.

Immutable Backups Are More Secure

This is where immutable backups come in, offering a new level of security in data backup strategies. As the name suggests, immutable backups provide an extra layer of protection by making data backups unchangeable – a fundamental characteristic in our current landscape of evolving cyber threats. When we speak of ‘immutability’ in the context of data, we refer to a state where, once written, data cannot be altered, modified, or deleted under any circumstances.

Immutability is particularly vital in the context of sophisticated ransomware attacks. Even if such an attack infiltrates a network, the original backup data remains intact and immune to tampering, providing a secure fallback option for organizations.

A well-established data storage principle facilitates this immutability – Write Once Read Many (WORM). WORM technology has been in use for many years in old optical and tape storage, where data can be written onto the storage medium once and then read many times but never overwritten or erased. Applied to modern data backups, WORM enables a reliable, secure backup solution. Once data is written onto a WORM device or system, it cannot be modified or deleted until the predefined retention period ends. This approach guarantees that backup data remains in its original state, safe from ransomware attacks.

The security of immutable backups resides in their very nature – their resistance to change. By implementing immutable backups in your data protection strategy, you add an indispensable tool to your arsenal, a tool that provides a secure safety net for your data in an increasingly hostile digital environment.

The Perils of Overlooking Immutable Backups

Neglecting the necessity of immutable backups can lead to severe consequences for all organizations. Without the security of immutability, an organization’s backup data is exposed to potential manipulation or destruction, leaving the organization with no fallback in the event of a disaster.

A notable real-life example is the City of Atlanta, which recently fell victim to a ransomware attack that encrypted a significant portion of the city’s data. Despite having backups, they were not immutable and rendered useless by the attackers, leading to losses amounting to millions of dollars.

The Imperative of Selecting a Backup Vendor Offering Immutability

Organizations need to partner with vendors that offer immutable backup solutions. This means not just choosing any backup provider but one that understands the importance of data immutability and has the tools to provide it. When selecting such a vendor, always ask pertinent questions about the vendor’s data protection strategies, their use of WORM storage, and how they ensure data immutability.

Implementing Immutable Backups in Your Organization

When developing an immutable backup strategy, key considerations include the volume of data you are backing up, the time it takes to restore the data, and where it is being backed up – in the Cloud or on-premise. Each of these factors will influence the design of your backup strategy. It’s also essential to understand the technologies and tools necessary for establishing immutable backups. And, of course, it’s crucial to communicate with your IT team to ensure they are aware of the importance of using immutable backups – before it’s too late.
