I've experienced 3 separate catastrophic data storage failures. Backups and even hard drive recovery did not help. In all three cases the problem that caused the failure was copied to the backups and corrupted the backup data along with the primary data. That included tape backup, hard drives, raid arrays, magnetic disks, CDs, and DVD backup storage.

When i was responsible for artwork at the company I work for, I did yearly hard copy backups and storage of all drawings and photos. The hard copies were also stored off-site. They do not do that any more, even after losing some product mechanical drawings.
