The bank I once worked had had a tape vault on the other end of the
parking lot. I think that hurricane Andrew may have changed their
strategy, and Chevron had an offsite backup when both the data center
and backup site were destroyed by Katrina. There are many good physical
backup companies, like Iron Mountain, but for personal backup, you just
gave to be aware of where you are storing your backups. Maybe store it
at a relatives home.
