    You can simply velidate the backup files integrity by restore verifyonly option.

    Unless the backup was taken WITH CHECKSUM, a restore verifyonly just checks the backup header and some metadata. It's entirely possible for a backup to verify but not restore.

    If the backup was taken WITH CHECKSUM, then a restore verifyonly is a good way to see if the backup will restore. If the backup wasn't taken WITH CHECKSUM, then the only way to be sure is by restoring the backup.

    A quick summary of the things you can do for database backup testing. The best thing you can do is to test the restore. There are some third party solutions that can help out. Let me know if you're interested.
