We considered the safety deposit box thing several years ago, but were
uneasy about putting tapes in a place where we didn't have 24x7
access. The way I do it now is keep the very most recent set of tapes in
my office, and the 2nd most recent at the other site, and it varies from
there on. Eventually I'll be looking at shifting a bagful of tapes each
week -- though not so many that I can't easily carry them. The person who
does this will be me most of the time, and I just can't afford the time it
would take to go to a bank once a week. And I need to be able to get at
those next-to-most-recent tapes relatively quickly when I need them, or
people won't want to rely on our backup system. (There aren't any banks
within two miles of where we're located, although it helps that our miles
are faster than those in East Lansing.)
However, one faculty member here didn't like my definition of "off-site,"
so I have lately been thinking of taking a smaller subset of the tapes that
won't rotate as frequently, and storing them farther away at an
off-off-site location. I may use a safety deposit box for that set.
Another option I once had in mind was a redundant set of tapes, but I've
abandoned that idea at least for now.

I'm thinking mostly of how easy it is to trigger a sprinkler system, even
when the fire is off in another corner of the building. Remember Ag Hall!

I will keep that in mind.
Thanks for the helpful information. It might be useful sometime to point
out that there are those who think I'm insufficiently paranoid!
