While I appreciate what you're trying to do, do you realize that
AMANDA's entire reason for being is to make backups easier by not
telling her what to do?  You are supposed to specify your tape and dump
cycles, and then let AMANDA figure out the rest.  She'll schedule full
dumps when she feels they're required, but the entire decision is based
on how you set up the tape and dump cycles.

AMANDA is a great backup program, but I see people trying to force
backup schedules all the time.  It's not needed.

You should subscribe to the AMANDA mailing list.  It has got to be one
of the best, if not the best, mailing list out there.  People are
insanely helpful.

Good luck,
