An immutable backup is a backup whose content cannot be modified, altered, or deleted, under any circumstances. The data remains unchangeable throughout its lifetime, guaranteeing its integrity even in the event of a cyberattack or disaster. This type of backup is a resilient solution against threats such as ransomware, doxware, spyware, and sophisticated man-in-the-middle attacks.
How immutable backup works
Immutable backup works like a digital safe. Data is stored securely, separately from the company’s production systems. It cannot be overwritten, encrypted, or modified, even if a workstation or server is infected with malware.
In practice, when ransomware is introduced through phishing or an internal vector, it can encrypt the network and attempt to reach all connected local backups. Thanks to immutability, the backup remains intact and allows critical information to be restored quickly without compromising the company’s integrity.
The benefits of immutable backup
- Maximum protection against cyberattacks: Attacks combining ransomware, doxware, or whaling cannot alter immutable data.
- Fast data availability: Essential services can be restored within a few hours, limiting the impact on operations.
- Resilience against disasters: Fire, flooding, or hardware failure do not affect securely stored immutable backups.
- Enhanced security: Backups are often encrypted and isolated from the production network, ensuring protection against intrusions or backdoors.
Why adopt immutable backup
Conventional backups are no longer enough in an environment where threats evolve rapidly. With immutable data, companies can recover quickly from an attack or data loss, significantly reducing downtime and financial impact. Without immutability, some organizations take weeks, or even months, to return to normal operations. Every sector is concerned, from SMEs to hospitals, local authorities, and universities.
