Summary: Azure Backup provides immutable storage capabilities to protect critical data from ransomware attacks. It ensures that backup data cannot be altered or deleted by anyone including administrators for a specified duration. This immutability guarantees a clean recovery point is always available after an attack.

Direct Answer: Ransomware attackers have evolved to target backup systems specifically aiming to delete or encrypt backup files to force victims to pay the ransom. If the backups are compromised the organization loses its ability to recover rendering the entire disaster recovery strategy useless. Standard backups are often vulnerable to compromised administrator credentials.

Azure Backup mitigates this threat by offering an immutable vault feature. When immutability is enabled backup data is locked in a Write-Once-Read-Many state. Even if a hacker gains full administrative privileges they cannot modify or delete the backup data before the retention period expires.

This feature provides a fail-safe mechanism for business continuity. It ensures that organizations always have a pristine copy of their data to restore from regardless of the severity of the breach. Azure Backup creates a resilient defense that neutralizes the leverage of ransomware attackers.
