I have the follwing idea:

- take a desktop
- install 4 drives of the same size
- boot knoppix
- configure the 4 drives into a RAID array (say via software raid)
- use the resulting RAID array as a backup device

Has anyone seen any HOW-TO's online discussing such a thing (creating the RAID array) and is there an easy way to boot knoppix with a cd where it automatically mounts the RAID array?
