Re: [Veritas-bu] Restoring from Multiplexed Backup

Thank you all for your inputs!

I am restoring using the bp restore command. All the mount points are selected for the one restore job.

./bprestore -C client -D source -f /tmp/restorefiles -R /tmp/rename -l -L /var/tmp/restore.out

The policy is configured to multiplex five streams to one tape drive. There is only one client in the policy.

The file list looks like:

/mount/point/1
/mount/point/2
/mount/point/3
/mount/point/4
/mount/point/6
/mount/point/6
.... and so on

NBU version is 6.0 MP4.

When I do the restore I am expecting to see all streams as separate jobs in the activity monitor. Sounds like I may need to use separate bprestore commands for each mount point? Hopefully this will not cause additional mounts/unmounts...

Thanks again,
Jeremy

Do you select all mount points at the same restore? If yes, then you will

Good questions, forgot to ask them :)

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.

MPX_RESTORE_DELAY = 30

Yup, change it in bp.conf.

Subject: [Veritas-bu] Restoring from Multiplexed Backup

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
