Not sure anyone has ever wanted to before.

Degraded mode is a mode where no level 0, full dumps,
are performed.  Only incrementals are done.  Of course
it is not possible to do incrementals only on new,
never dumped, DLE's.  They must get a level 0 first.

I guess, if you really wanted to mimic degraded mode
you could set the dumptype options like "increment only"
or strategy no-full.  I forget the actual names.

Why do you want to force degraded mode?

Have you checked your holding disk for size, permissions,
and the amanda.conf parameter "reserve"?  It defaults to
100% (i.e. 100% for degraded mode, none for normal mode)
which doesn't sound like what you want.
