Make sure you test restores periodically! I had a co-worker who got fired when they tried to reformat a failing disk instead of sending it out for recovery and felt safe because the user "had tape backups." Those were DLTs and perhaps today such failure would be a lot less likely but still. Just do it. Part of basic tape/backup hygiene.
