The short answer is that you can't, least not like you think of full
and incremental backups. Amanda rotates full and incrementals. If
you have, say 3 sets of tapes, and dumpcycle is two sets, on any given
backup half the backups on the set are full and half incremental. The
next backup, the other half are full. To get something approximating
what you want, have two different configurations, say Weekly and
Monthly. The tapes are divided (and labeled) for the two
configurations. The configurations are almost the same, just the
label and dumpcycles differ. The disklist file can be the same file
(hardlink) for both.

I use cron jobs to run my every other day backups in the middle of the
night. A cron job also runs the day before with amcheck to make sure
the right tape is in the drive. My semi-monthly backups are done by
hand from the command line and the tapes stored off-site.

I will look at you configuration file when I get home (Saturday) and
can compare it to my own.
