As I've learned to my sorrow, no amount of RAID will protect you against
a misplaced 'rm -rf'.

I would love to have a *real* backup of my music collection.
Unfortunately, by "real" I mean some sort of relatively stable media
that can be put in a safe deposit box or something -- i.e. a USB disk
drive is out.  To the extent that I've looked, tape solutions are just
too damn expensive.
