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.
And there's where your thinking diverges from the TSM client coders'
thinking. It's not an option for the _filesystem_; it's an option for
the _backup run_.
You're in the position that the snapshot you want to use has a stable
name. There are folks who have snapshots named related to the date of
consistency-point. If your snapshots naturally came out as
/nasfs/.snapshots/2012-07-08-19-00-05
you wouldn't naturally think of the snapshot location as a statically
configured fact.
If you're already preschedcmding, you might use that step to calculate
the command lines to run the per-filespace "dsmc incr" lines, drop
them in a temporary script, and then run that as a COMMAND schedule
instead of an INCREMENTAL sched.
