Nope, that’s the only way.

Restoring from Multiplexed Backup
Curtis,
Thank you for your reply.
I have tried your suggestion and it is working. I see a slight performance increase
when doing the mpx restore now, which should translate to higher gains when
restoring more data.
One more question for everyone: I need to rename files as well. Is the best
option to use bprestore -R <renamefile> or is there another trick that works
better? Can I use the same rename file for each bprestore command or should I
make one for each stream?
Thanks again,
Jeremy

It's been a while since I tested this, but _I_ remember that if you wanted it to
restore the way he wants, you HAD to issue five different restores at the same
time and use the restore delay feature to start them at the same time. If
you just selected five directories, it did them one at a time. That's why
I always did my multi-filesystem restores as a loop
for I in /a /b /c /d /e
do
bprestore $I
done

Do you select all mount points at the same
restore? If yes, then you will see only one job, but netbackup will
restore all files in one tape pass.
If you start 5 restores the you have to be
fast (every restore must start within 30 sec, by default). This can be changed
from master server properties.

Hello,
I have a standard backup policy configured to stream five mount points to one
tape drive. This is working fine.
When I do the restore, I only see one stream restoring at a time. Is it
possible to restore the five streams of data from the multiplexed tape at the
same time?
Other backup softwarescan do this so I assume Netbackup can as well... if some
could please point me in the right direction it would be much appreciated.
My environment looks like this:
Master: Solaris 10 on SPARC
Media Server: HP-UX on PA-RISC
Source Client: HP-UX on PA-RISC
Target Client: HP-UX on PA-RISC
Multistream = 5
Multiplex = 5
One LTO-1 tape drive
Thank you in advance for any insights.
Jeremy
