Re: [Veritas-bu] 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 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?

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...

[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.

Re: [Veritas-bu] Drive Multiplexing
Thanks Justin. I think using two policies for this going to work. The NEW_STREAM directive and individual pathnames is streaming five file systems at a time to one tape drive. Now on to testing restores! Thanks again for your help.

Re: [Veritas-bu] Drive Multiplexing
Dean and Justin, Thank you very much for your replies. I need to use ALL_LOCAL_DRIVES (I think) because there are two clients in my policy. Basically the backup runs like this: 1. - client1: make clones of production file systems 2. - client2: mount clones of client1's production file systems 3. - client2: back up client1's production file systems to local tape drive 4. - client2: back up client1's root volume group over the network. client1 is only a client, client2 is a client and a media server. Am I able to specify the pathnames in this configuration, or am I stuck with ALL_LOCAL_DRIVES?

[Veritas-bu] Drive Multiplexing
Hello, I am trying to achieve the streaming of five mount points on an HP-UX client to one LTO-1 tape drive. I have run into a strange issue though. If I set multistreaming to five, and multiplexing to five, I see each stream as a job in the activity monitor. However, NBU is breaking up each mount point into five streams - not what I want. I want one stream for each mount point. Symantec support has instructed me to turn off multistreaming in the policy, and leave multiplexing set to five. When I do this, there is only one job in the activity monitor for the client, and I cannot verify that I am multiplexing the mount points to the tape drive. Also performance is not what it should be for this backup, running at 13 hours instead of the five or six I would normally expect for roughly 420 gb of data. My environment looks like this: Master = SPARC / Solaris 10 / NBU 6.0 MP4 Media Server = PA-RISC / HP-UX 11.11 / NBU 6.0 MP 4 Client = PA-RISC / HP-UX 11.11 / NBU 6.0 MP 4 I am using the ALL_LOCAL_DRIVES directive, with an exclude_list of "/". I have an include_list that specifies the mount points I want to back up. Does anyone have any suggestions that will help me to verify that I am in fact multiplexing the mount points to the tape drive during the backup? Any suggestions and feedback are welcome. Thank you for your help. Regards, Jeremy ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
