Why would you want to do RAID for a backup machine? Assuming we are
talking disks full of backups, you already have 2 copies of that data,
so you are not in trouble if a drive fails, you just put up a new one
and backup the original data again.
RAID is for systems that need to be always up, that dare not be taken
down to replace a drive etc. That's not true of backup servers.
