I disagree... usually scanning for changed files takes long because the
disk is busy, either just for scanning or from other tasks as well.
Using more client instances on that one disk(-array) would just make
the disk more busy.

You could try upping the resourceutilasation of the client and the
maxnummp, this might help a bit, recent AIX clients actually do
multi-session backups and restores, but if the disk is the bottleneck,
it doesn't help.

If your server is a bottleneck, you might tnink about
incremental-by-date backups, but I'd recommend faster disk (or more) for
the database and log....
