Automated test restores Are you sticking with the legacy format or do you plan to move to the new backup format? If new backup format, you can use Restore Verification if what you're after is image restore verification. If you want to test a file-level restore from a VM or Image, then you can set up a scheduled restore that restores a single common Windows file.
Or, as an alternative, or for file-level backups, you can create a dummy file in the same location on every computer and make sure it's backed up . That way you can test restores if you need by restoring this dummy file.
But I have not run into any customers doing this. I've probably asked before, but what is your major concern? Is it image/VM backup with a broken incremental chain, a corrupted backup file, something else? Is it only for image/VM or are you concerned about file backups too?
Also, the new backup format performs backup consistency checks every backup to ensure the backup sets are in backup storage and they are the correct ones. That's an additional check that is not performed by the legacy format. In cases, where you have a full backup and chained incremental backups, the new backup format avoids backup set integrity issues (like a missing incremental) by performing this check and escalating to a new full backup if it detects an issue.
