That's harder to do with Amanda because when a level 0 is done is not
deterministic (well, it is, but it's much more complicated than "it's
Thursday").
>Can I add as many new ones as I want then? ...
Yup.
>And yet there are over 100 tapes in the tapelist file!
That just means the tapecycle value didn't get updated when more tapes
were added. If tapelist has less entries than tapecycle, Amanda will
ask for new tapes. But if it has more, Amanda just cycles through them
and pays no attention to tapecycle.
Tapecycle is used for some other things (how long to keep some log files).

Yes. But notice what you said. "At least", not "Every". In other words,
it might only be a couple of days between doing level 0's or it might be
the full four weeks. It's all up to how Amanda wants to balance the load.

Correct, without taking other action to save that data.
