Allen,

No, I'm sure you could put "-snapshotroot=xxx" in the options argument to the 
client scheduler.  But your response made me realize that I left out one 
relevant point:  We are backing up several NAS volumes via the scheduler, not 
just one.  We use the pre- and post- scheduler exits to mount and unmount those 
volumes.

So, we would need to specify a snapshotroot 'target' for each volume that we 
want to backup.  It seems this is what 'include.fs' was designed for, to 
specify fs-specific options.
