Why each option
Properly testing a disaster recovery backup plan requires actually restoring the backed-up data to a test server, not just verifying that backups ran or that media is readable.
An integrity test only verifies the physical condition of the backup media, not whether the data stored on it is complete or restorable.
Verifying that data can be read confirms accessibility but does not prove a full system or application restore can be completed successfully.
Reviewing logs only confirms that a backup job was initiated and reported success, not that the resulting backup is actually usable for recovery.
Restoring backed-up data to a test server is the only method that fully validates the entire recovery process end to end. It confirms not only that the data was captured but also that it can be successfully retrieved and used to bring systems back online. This directly tests the disaster recovery objective, which is to recover operations from a backup.
