> [backup on harddisk]

CDs won't really cut it for me either.  CDs
have very limited capacity.  Same story with
DVD or even tape backup,  unless I am prepared
to spend mucho pesetas.  (IBM has a pretty
cool looking 100 GByte tape drive.  The tapes
alone go for a couple hundred US bucks.)

I recently added a Promise RAID SATA controller
and two SATA disks (160 GByte each) to my system.
The Promise does hardware RAID 0 and 1 (I don't
remember whether it also does 0+1).  I'm using
mirroring.

All the important data is now on that "one
mirrored disk".  If one of the physical disks
fails,  I can simply install in place of the
failed disk a new disk of equal or greater
capacity to restore the mirror.

The Promise has four SATA ports,  enough for
two disk pairs,  and I'm thinking of adding
the second pair,  as I need additional
"mirrored" capacity for an upcoming project.
