7 x runtapes (which is the number of tapes used per run)

After every run - amanda is a backup solution for people who are serious
about backing up their data, and that means that you don't put a number of
backups one after the other on one tape.

You can't do that, or at least not with the above spec. You could have
dumpcycle 7 days   and  runspercycle 1  but you probably don't want to do
that :-) (because you'd only be backing up once per week) With 15 tapes,
assuming that you backup on weekdays only, and have sufficient tape
capacity, you'll get only three weeks history.
