Exactly. RAID above RAID 0 does provide redundancy towards hard disk errors.
It makes the system more robust. But the data is still in the same set of
drives. Backup, as with scp, rsync and cron to a different computer is what
you need. We backup our computers every hour with the above. It's very low
impact and all we can loose are some changes in the last two hours if the
system dies during rsync.
David, RAID 0 is not mirroring. What it does is extend capacity over two or
more drives. RAID 1 is mirroring.
