No.  The "length" parameter in your amanda.conf tapetype section controls
what will fit.  The "tapetype" utility is just a tool to help figure
out the amanda.conf parameters.

That's what I do.  Don't go nuts with the number :-).  For my particular
type of data, 20%-30% is about all I get.

Make sure you don't also use software compression.  Compressing things
twice usually expands them.

What's in /etc/dumpdates doesn't matter.  It's whether Amanda did a
backup before.

That's a possibility.  I didn't look at the code to be sure, but why
don't you use "dumpcycle 0" in amanda.conf instead of running the "force"?
That's the usual method to ask Amanda to do only full dumps.
