Physical tape shipment is scrutinized here. Tapes must either be
encrypted or hand-carried by a Bank employee to their destination.
We'll probably be moving to an all-VTS environment in a year or two,
which makes shipment even more of a problem. When I implemented the
remote DR process, I added the capability to fall back to local tapes.
After a few years of never using it, I took the code out and we freed up
the tape range for something else. If the channel extension is down,
the offsite backups just wait for it to come back up.
