Suppose  you have a large DLE that rarely changes (archived data,
videos, isos, or somesuch).  If your normal dumpcycle is a week,
you will be writing it all to tape every week and using a lot of
tape over the course of your tapecycle.  Also, planner has to work
around that large dump every dumpcycle.  If you make it a separate
config, you just back it up when it changes, and won't need to back
it up again until the next change, which might be months later, saving
lots of tape and dump time.
   I recall someone suggesting making it part of the regular config
and commenting the DLE out between changes, but if you do that you
run the risk of having it fall off the back end of your tapecyle f
you go a long time without changes.
   Whether or not a separate DLE is the right thing to do would depend
on the size of the data, how often it changes, and how sure you are
that you will be aware of changes and remember to run the backup.
