Please don't take this the wrong way, but you don't know what you're talking about. RAID is not a backup, and backup is not RAID.
RAID is keeping going with a hard drive failure. Backup is where you can recover any file in your backup time frame. If in a RAID configuration you delete a file and suddenly realize three months later that you really should have kept it, you're out of luck. If your OS decides to crap garbage all over your disk, RAID will faithfully mirror that garbage for you. It's good to have RAID, but it's also good to have backups.
