Rotating tape sets for offsite storage

[Dan Smith]

What can I do if I want to, once every two months, rotate a tapeset offsite?  I
run 14 tapes per cycle (2 weeks) and don't want to mail stuff every
two weeks, but wouldn't mind every two months.  Is there a way to do
this other than having two different conf's?  If I have to use two
confs, can I have them use the same data dirs, like indexes, etc?
