I think in the case of having to run 2 backups jobs I would run one
backup job and then run a utility job to copy the 1st set of tapes to
the remote set of tapes.

told to do this. If this is possible, then you could fill a tape up to,
say, 80% and be fairly confident that the second tape would be long

Now that is interesting. How does that OS
There is a round about way of doing this. Fran and I came up with it about 4

Can't do that, unless you can guarantee that the tapes at the remote

are longer than the local copy (which would be unlikely). When the

runs, writing to a given pair of tapes ends when the first one hits
EOT.
That's yet another complication for us if were to use twins. We use
