Sorry to be dense. This is a new concept to me, so I'm struggling to get my
thoughts straight on it.
Perhaps an example will help me.
I (like you) have 5 vtapes (BTW are yours the same size as the physical
tapes ?) mine wind up being smaller. I want to rotate 25 tapes.
I see the benefit of having the 3 configs, and I will follow your example
there. I had missed the fact that if I did not set up a vtape only one, I
would have to mount the tape. This would defeat the purpose of being able
to recover, while a backup is running.
Both the vtape, and the physical tape need to have the same label, correct?
The tape will carry it's label with it, and I am thinking that I can
overwrite the label on the vtape as needed. Thus after the firs 5 days, the
vatpaes would be DailyDump00 -> 04, and I would have the same physical
tapes. On day 6 of the run I would insert a new tape. Then I would label
it, and slot 1 of the vtape changer with the label DailyDump05, and so
forth. But I can't see how I can do this without having to _always_ run
amalbel. Which I would prefer not to do.
Is that what your script address?
