Re: [Veritas-bu] Restoring from Multiplexed Backup
Even if it's restoring all the filesystems simultaneously, you'll only
see one job if you only kick off one restore. I suggest you use my for
loop example, as it's very easy to type and you don't have to worry
about the restore delay, as they'll all be issued within a second of
each other.
Also, another reason why I always did my multi-filesystem restores in a
loop was that when one of them failed, you knew which one and you could
just fix and rerun that one. Doing them all in the same job makes
reporting a bit muddled.

Subject: 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

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.

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.

This is how it works by default, I backup 3 directories and I see files in all 3 of them being restored at the same time. When you backup to you see 5 simultaneous jobs writing to tape at the same time from the same client? > > 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. What does your policy look like? What version of NetBackup? Only an LTO-1 tape how fast are you feeding the drive? What are you expecting? The way it works by default if you backup 5 directories with 5 mpx when you restore it will happen the same way AS LONG AS when it backs up you see all 5 backing up at the same time. (Also, I do not use any policies with the NEW_STREAM directive) so I do not know if that could be affecting it, what does your file list look like? > > 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 > ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
[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.
