Duplicate RAID drive as the working storage, to protect against hard drive falures. The drives are on different disk controllers.
But that's not really backup.
For backup I use two external USB drives. Each contains a full backup. Because if you only have one backup, then when the working storage fails, you have no backups left -- your backup just transmorphed into the vital only copy.
There's a plan to regularly swap drives with a friend, but that hasn't materialized yet.
