Tom,
I believe what you've stated is true, you could use EXCLUDE
in conjunction with NEW_STREAM to get multiple simultaneous
dumps going.
There's a simpler and easier way to accomplish this, however.
Use EXCLUDE when you want write less data to tape. Use
NEW_STREAM when you want to initiate multiple simultaneous
dumps from the same class.
>From a performance perspective, an EXCLUDE based dump can be
less efficient than a full volume dump, or a quota tree based
dump. This goes back to what I said earlier, use EXCLUDE to
write less data to tape, use multiple simultaneous dumps to
write to more than one tape drive at a time.
Dump performance is enhanced with Data ONTAP 6.0 or higher.
Full volume or quota tree based dumps will provide the best
performance.
Let me know if you require more detail.
Thanks, Bill Roth

How about if you wanted to back up A and B to one tape drive, and C,D,E to
another? Could you allow multiple data streams and then
SET EXCLUDE = C,D,E
/vol/vol1
SET EXCLUDE = A,B
/vol/vol1
?
Thanks,
Tom

Joel,
Actually, setting the EXCLUDE environmental variable within a
NetBackup file list does work, but necessarily the way you
might think it works.
Here's an example:
The subject volume, /vol/vol1, consists of five subdirectories,
not contained in quota trees. The five subdirectories are A, B,
C, D, and E.
To back up only the A and B subdirectories, the file list would look
like this;
SET EXCLUDE = C,D,E
/vol/vol1
In this example, the /vol/vol1/C, /vol/vol1/D, and /vol/vol1/E
subdirectories are not dumped to tape.
Thanks, Bill Roth

I never saw an answer to this on this mailing list and I just figured it out
for myself so I thought I'd answer it.
To exclude files using Veritas you have to use a directive like follows:
SET EXCLUDE=*.PST
This directive is passed directly to the NDMP process and is ignored by
Netbackup.
