Why should administrators periodically simulate ransomware recovery using SnapRestore?

Simulating a recovery is a critical component of any robust data protection or disaster recovery strategy. By periodically using SnapRestore to revert a non-production volume from an immutable Snapshot copy, administrators can validate the entire recovery workflow. This test confirms the integrity of the backup data, ensures the restoration technology functions as expected, and verifies that the recovery time objectives (RTOs) can be met. It is the only way to have confidence in the ability to recover successfully from a real ransomware attack.

A. SnapRestore is a data recovery tool that reverts a volume to a point in time; it is not designed for or used for defragmentation.

C. Simulating a recovery does not manage or delete compliance logs; log retention is handled by separate lifecycle policies.

D. Data recovery operations like SnapRestore do not inherently improve storage efficiency metrics such as deduplication ratios.

Regularly test your restore procedures to ensure that they work and that you can meet your recovery time objectives (RTOs)." (Section: Recovery, p. 16).
