It's in the relationships among (taking from my configuration):

     dumpcycle 1 weeks       # the number of days in the normal dump cycle
     runspercycle 5          # the number of amdump runs in dumpcycle days
     tapecycle 30 tapes      # the number of tapes in rotation

this says that I'm going to run 5 times a week, and I have a cycle of 30
tapes. When it gets to the end of 30 tapes, it will ask for the first
one again. Or, if you have more, it will take any unused, labeled tape,
or any that is 30 or more runs previous.

I have 35 tapes. But I've set 5 of them to "no-reuse", so they are a
sort of archive. I cycle through the other 30.
