Thanks to all for some great suggestions.
My initial addition was a simple list of EXCLUDE.DIR for each of the currently
existing folders below J:\IMAGENOW that are not to be traversed.
That cut backup time from 24+ hours down to 15 hours.
We're running two nodes on that server, with slight changes in the dsm.opt to
have one responsible for a given path, the other node for another path.
The manager of that server insists that new paths won't be created; we'll see
if that's true, 'eh?
Thanks again to everyone.

Harold,
It sounds as if you need a multiplexed session solution. You might want to
check out dsmISI MAGS. It is a utility that manages many simultaneous Spectrum
Protect sessions running in parallel.

One of my clients has a server running ImageNow. There are millions of files
and several thousand folders that take over 24 hours for the daily incremental.
My goal is to backup a single ImageNow folder and reduce the elapsed time to
traverse thousands of folders that don't need to be backed up.
We worked out a setup for a new node in an effort to backup only a given path
within the ImageNow structure.
The following dsm.opt statements are in place:
DOMAIN J:
EXCLUDE J:\...\*
INCLUDE J:\IMAGENOW\SUBOB_OSM\...\*
That was successful in backing up only the files and subfolders/files in
SUBOB_OSM. But it also backed up thousands of directories on J:\. Most of
them are in the \IMAGENOW path.
My plan is to add a few EXCLUDE.DIR statements such as:
EXCLUDE.DIR J:\IMAGENOW\54_OSM
EXCLUDE.DIR J:\IMAGENOW\DEFAULT_OSM
The question: will adding EXCLUDE.DIR now, after the node has backed up all
those paths, result in a performance improvement?
I suspect Spectrum Protect server will send all the directory names to the
node, but hopefully the work on the node side will be much faster.
Or, will we need to delete the filespace, then start over with a fresh
"incremental forever" backup to clear out all that directory structure?
Thanks.
