41 Are they even being done? Who? What? When? Where? How?

42 Why do you care about restores? Has it ever been tested? SQL Developer Edition = CHEAP Your backups are only as good as it s ability to restore

43 Do we really need this? Really? Did you just ask that? My Typical Solution? Restore most recent backup to another server (even your workstation if you must) Run DBCC CHECKDB( ) command Verify Database Verify Restore process works
