Yes, if you have only one DLE Amanda obviously can't spread
its full dump over several days.  You could use tar instead
of dump, and make each subdirectory a separate DLE, then the
fulls could be spread out.
   If the you do that, you might want to also leave the top
level directory as a DLE with an exclude file listing the
subdirectories that are separate DLEs.  That way if a new
subdirectory is created, and you forget to update your config,
the new subdirectory will still be backed up.
