You don't use hard drives to back-up something this important, you use tape: http://www.oracle.com/us/products/s...e/tape-storage/t10000c-tape-drive-292151.html
Tape won't help you if your building floods, burns or suffers some other catastrophe. Off site backups are the best way to go for really important stuff like source code and financial records.
