For what its (belatedly) work, I use amanda with:

dumpcycle 7 days
runspercycle 5
tapecycle 10 tapes

And this gives me 1 full dump of each filesystem once each week. This
leaves me with the "current" set, plus last week's set.

(I recall this was right out of the Unix Backup & Recovery book..)

My backups run monday AM through friday AM.

I'm not sure what the original poster was actually looking to achieve
though...
