An immutable backup uses WORM or object lock so data cannot be changed or deleted for a set period, protecting recovery points against ransomware.
Immutable Backup Definition: An immutable backup uses WORM or object lock so data cannot be changed or deleted for a set period, protecting recovery points against ransomware.
An immutable backup is a copy of data written in a way that cannot be altered, encrypted, or deleted for a defined retention period, typically using WORM write once read many storage or object lock. Immutability protects backups against ransomware and malicious insiders, ensuring a clean recovery point even if production systems and other copies are compromised. It is a key element of a resilient strategy such as the 3-2-1-1 rule, which adds an immutable or offline copy to the classic 3-2-1 approach.
