We used to use DVD's for off-site backup, but that's not been the best
of solutions. I've been experimenting with external hard drives but
I am less comfortable with them; I've seen too many drives fail. The
idea of letting them sit for awhile and praying they spin up later
bothers me. :-) On the other hand, running Unison to a server someplace
else has obvious benefits and some downsides too. Backups remain a
tricky problem to get right.
