I am not sure what you are trying to accomplish, but in general I don't
believe you can ever force Amanda to do a level N+1 dump if level N is
already empty. (This makes sense, in that there's no reason to require
the operator to pull N+1 tapes for recovery if N tapes will give you the
same result....) So if your DLE doesn't change every day (or only has
very small changes), I don't believe you'll be able to strictly enforce
the rule as described.
But to see the knobs you can tune to get closer to what you want, see
the the four bump options (bumpdays, bumpmult, bumppercent, bumpsize)
in the amandna.conf(5) man page (in both the global and DUMPTYPE
sections).
Also, to see the thresholds that Amanda calculates based on those
parameters you can use the the "amadmin .... bumpsize" command (though
I guess that command only looks at the global bump options, not any
dumptype-specific ones).
