Backups must be restorable within 15 minutes after a failure.
Validate the recovery procedure regularly rather than checking only that files exist.
Which operational practice is most appropriate?
Restore backups into an isolated environment on a schedule and measure the actual recovery time against the RTO.
Detailed explanation
A restore test validates both recoverability and the actual time required by the procedure.

Foundation review
Recoverability evidence
A successful backup job does not prove that the restore procedure will work under pressure.
Measured recovery
Timing the restore exposes procedural, permission, and capacity gaps before an outage.
