In a data backup strategy, which action helps ensure recoverability after a failure?

• A. Backups are optional
• B. Testing the restore process
• C. Relying solely on uptime
• D. Only keeping one backup copy

Answer: (B)

Regularly testing the restore process is essential for recoverability because backups are only useful if you can actually restore data from them when needed. A restore test validates that the backup contains intact, readable data and that your restoration steps, tools, and procedures work as documented. It also helps verify the required personnel know how to execute the recovery quickly, which supports meeting recovery time objectives. Without testing, you might discover too late that backups are incomplete, corrupted, or incompatible with the restoration process, leaving you unable to recover after a failure. In contrast, making backups optional, relying solely on uptime, or keeping only one copy greatly increases the risk that data cannot be recovered or that recovery takes impractically long.
