Subject: [Veritas-bu] DSU Question.

Hi,

I'm still in the mist of a backup design to use either a DSU or a DSSU
target for my interim backups.

Would like to know if there's a limitation in the number of streams if
the storage unit is a DSU? I also assume multiplexing will not be a
issue if the target is DSU right?

Another senario is, if i were to use backup direct to tape, i have a
backup that require to run the bpstart notify script to do some export
dump and it might take 30mins or more, the backup will actually hog the
drive during the export dump and if there's another small backup that
trigger during that time will be put in queue.

Given the same senario, if my storage unit is a DSU, will the small
backup job go through as there is no tape drive involved.

Appreciate anyone of you having such a configuration to share your
experiences. Thanks
