Looking for something that would preview the amount of data if I ran an
INCREMENTAL on the currently defined DOMAIN on the client. Preview just
gives me what would be included/excluded based on the filespec specified and
the current include/exclude list. I don't think this is really what they
want to do as it includes the whole filespace information from the TSM
server to compare/build lists. Been thinking about using -INCRBYDATE on the
systems that really don't qualify for a journal and also SKIPNTPERMISSIONS
to take that out of the equation.

Unless I configure them for the journal and use the unsupported utilities to
list out the journal and maybe massage it with Perl or something.

Try  dsmc PREview  and see if it provides the info you seek.

An in-client preview can't tell you how long a networked backup is going to
take or gauge the effects of a large Incremental contending for memory with
other apps in the client system, where paging can cripple a backup.  I'd
advise performing analysis to identify the slowest ingredients in your
backups and see if they can be addressed.  Exploration of journal-based
backups or target area backups may be in order.
