Well actually we do it from command line
but I take your point.
I was pretty sure I could start separate
restores to force it to do this but was wondering why it required that given
that it didn’t before when it was three streams backed up so they had
different backupIDs.
Unfortunately for this particular restore
I’m having to do it over the public LAN because the server in question
only has 1 interface. I doubt having 3 streams going would save much time
here. On the one I’d done previously it was over a backup LAN using
Gigabit Ethernet so 3 streams might have helped.
Surprisingly though this one isn’t
going quite as slowly as prior tape restores over the network – I’d
have thought the network would have been the bottleneck but this makes it
appear it is somehow more cleanly transferring the files even across the LAN.

Jeff,
The way that Data
Domain restores is down to how you submit the restore jobs from the backup and
restore console in NBU. If you want to restore root, usr and var you
could click on root, uncheck the mountpoints you don’t want to restore
and kick off the restore. That will restore everything in 1 job. If
you drill down and only select the individual mountpoints you want and kick
each one off as an individual restore, Data Domain will send data to multiple
restore jobs.
As an FYI we found
that we were able to restore our biggest database (Exchange) quicker in a
single stream than in multiple streams. A single stream allowed us to
restore approximately 100GB per hour.

Subject: [Veritas-bu] Restore from
Data Domain using 3 selections
For
the second time I’ve noticed that a backup we created that had 3
simultaneous selections going to Data Domain (as it previously did to tape) on
restore is only doing a single selection. When we did this to tape
it would restore 3 different selections simultaneously just as it had backed
them up.
Is
there something I need to tell bprestore to force it to do this when the 3
selections were all going to the same location like a Data Domain?
If not would starting 3 separate restores of only the files in the specific
selections cause it to run concurrently?
