What practice helps verify that backups remain recoverable and usable over time?

• A. Automatic integrity checks during backup
• B. Periodic test restores to verify recoverability
• C. Rely on vendor certification
• D. Do nothing

Answer: (B)

Regularly performing restore tests is how you prove a backup can actually be used when needed. Integrity checks during backup help catch corruption at the moment of backup, but they don’t guarantee that a restore will succeed weeks or months later in your environment, with the right keys, credentials, and system state. Vendor certifications are external assurances that don’t reflect your specific setup, and doing nothing leaves you blind to recoverability until a real outage. By scheduling periodic test restores—ideally in an isolated environment—you verify that the backup sets are complete and readable, that the data is intact and consistent, and that the restoration steps work as expected. This includes validating full system restores as well as granular recoveries, and confirming you can meet the required recovery time. Regular restoration testing helps you uncover issues like missing backups, corrupted media, or misconfigured restore procedures before you actually need to recover.
