Which of the following best describes the purpose of testing backups?

• A. To confirm restorations are possible after data loss
• B. To validate encryption
• C. To verify hardware compatibility
• D. To measure backup speed

Answer: (A)

Testing backups focuses on recoverability. The essential reason to test backups is to confirm you can restore data after loss and return systems to a usable state. This means the backup copies are complete, uncorrupted, and compatible with the target systems, and that the restoration procedures work smoothly in a real recovery scenario. Regular restore testing also verifies that the restored data reflects the correct point in time and that staff can perform the restore within the required timeframes (meeting RTO and RPO). While aspects like encryption, hardware compatibility, and backup speed are important parts of a broader strategy, they do not address whether you can actually recover data when needed—testing backups ensures that critical recoveries are reliably possible.
