Yes, I was going to suggest the service bureau contract-style approach as
well, possibly/probably with a line item to migrate and consolidate the
tape contents to latest media (e.g. TS1130) in duplicate or triplicate (and
duplicate or triplicate sites), and probably encrypt the data as well (with
well-protected keys, with the proviso that losing the keys means losing the
data). That'll preserve and protect the data for the longest period going
forward.

Another idea: keep the mainframe in-house but put it "on ice" unless and
until needed to read some data. This is basically (or actually) free unless
and until the company needs some data, then there's a price. Slight
modification to that: trade-in the residual value of the machine for a
System z10 BC Model A01, perhaps/probably also with a TS1130 drive or two,
perhaps at zero net cost depending on what you've got to surrender. Put the
BC on cold standby. Keep a set of (encrypted) tapes, and send one (or a
couple) sets off-site. That would give your company the longest technical
runway to preserve reasonably convenient future data access.

....Dumb question, but didn't anybody think of this problem before, say,
December 31, 2008? It's a rather important issue -- corporate data
archiving, retention, protection, and access -- don't you think?
