I think we were doing 60 full tapes a week, with the disk partitions sized
such that it was some number of integer multiple disk partitions per tape.
A minimum of 60 incremental tapes, as they could ask for additional tapes.
We kept tapes for a three week rotation, but occasionally would end up with
double that number in the database. We have a 3 week rotation schedule,
with something under 60k volumes, and almost everything got backed up. We
did one full tape per volume set.
We stopped using the AFS backup system two weeks ago.
