The answer to your question is depending on how much tapes you want to use,
how convenient is for you to make backups, how much data change and how often...

You have a good tape rotation example in the dump man page towards
the end.

You can simplify that example by doing each day of the week a level-2
dump instead of the full Hanoï sequence (3 2 5 4 7), this way you'll
have only 3 backups: the full one (to be taken depending on how much
data change, once a month or once a year), the level-1 one to be taken
once a week and the level-2 which has the up-to-date changes since the 
latest weekly dump.
