Re: [Veritas-bu] How important is Processing Power?
CPU speed is important for backups but more important is the ability of the system to traffic the data from the network to the drives. (I/O traffic). You must be sure that you are using the capabilities of the system right. Put the nics and the fiber(or scsi) cards in a separate PCI bus. BUT the real important consideration in CPU power and memory is the restores. If you want to restore a system with many small files and you dont have enough power you may wait for a long time for the restore to start. This is because NetBackup starts to seek for the files at the database and compare them with other files. ---Original Message--- From: Veritas Netbackup [EMAIL PROTECTED] Subject: Re: [Veritas-bu] How important is Processing Power? Sent: 22 Sep '06 21:50 Hi Jon, Processing power is important, a month ago I had posted to the list and I got some real good inputs from our gurus. We use Sun Fire 6900 server with dual core processors, by merely upgrading to high clock speed processors, we have observed improved performance in read writes and also avoiding the backups from aborting with 155. We backup arnd 10 TB a day and use 4 dual core SPARC procs of 1500 Mhz. I have learnt from the list and some docs that having multiple media servers helps see a quantum leap in performance.

Not only is there the added server expense, but both Windows and NBU licenses for multiple processors are more expensive. We're looking at Intel Dual Core Xeon 5060s w/ 2x2MB Cache, 3.2Ghz, 1066Mhz FSB on a Dell Power Edge 2950 w/ 4GB RAM. I originally spec'd two processors (two dual cores) which I'm certain will be quite powerful enough to drive 4 Gigabit nics to disk over fiber. But how important is it, and can 1 do the job? Anyone running anything similar? -Jonathan ___ Veritas-bu maillist - [LINK: mailto:[EMAIL PROTECTED] Veritas-bu@mailman.eng.auburn.edu [LINK: http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu] http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu ___ Veritas-bu maillist - [LINK: [EMAIL PROTECTED] Veritas-bu@mailman.eng.auburn.edu [LINK: http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu] http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
Re: [Veritas-bu] Small files FS backup too slow
Use multiple data streams. Make a file list splitting the directories of that drive letter to 10 streams (ore more). Back them up together. The better way to deal with this is to implement advanced client. It will backed up this drive as a row drive (fast) and will give you the opportunity to do individual file restores. ---Original Message--- From: Veritas Netbackup [EMAIL PROTECTED] Subject: [Veritas-bu] Small files FS backup too slow Sent: 23 Sep '06 21:26 We have a Windows 2003 client, I have installed NB with MP4 patch. The D:\ drive has directories with small log files in thousands, now that we have increased the client timeout to 1800, the backups seem to start, but the estimation and backup of the files seem to take forever. Just while I was leaving office today, the backup was running at a snails pace of about 80Kbytes per sec. The NT backup as per the Windows admin finishes in about 1/2 hr. Netbackup of C:\ and H:\ drives are fine.

Re: [Veritas-bu] How do we duplicate skipped images in vaulting
We run with the Vault permanentlyset to level
5logging. Info for failed images is then captured in the sessions
directory in the log for that particular vault stream. You can tell from the
activity monitor which duplicating session failed as it will say something like
10 of 12 images duplicated. You then look in that sessionlog for the
specific problem. e.g.
03:19:23 INF - Beginning duplicate on server ccobkp01
of client ccovcs01.03:19:25 INF - Beginning duplication on server ccobkp01
of client ccovcs01, creating copy 2 on destination media id GC901203:38:14
INF - host ccobkp01 backupid ccovcs01_1157711364 write failed, media write error
(84).
or
05:27:39 INF - Duplicating policy SQLLog schedule
SQLLog backup id ccobwpci01_1157990414 copy 1 created on 09/12/2006 04:00:14 on
source path E:\05:27:39 INF - Backupid ccobwpci01_1157990414 copy 2 already
exists05:27:39 INF - Duplicate of backup id ccobwpci01_1157990414 failed,
the entity already exists (226).
One of the reports generated during the eject phase
also lists images that have not been duplicated.

vaulting
Yes thats true,The problem is that I have just enough VTL
space to hold data for 3 days. We engage 8 Gen3 drives 3-3-2 for the vaults {3
at at time}. We are in the process of changing the polcies to implement daily
vaulting, but would take some time. For now it happens that we are not able to
overlap one of the vaults in the 3 day period. Thus we end up loosing some
images.How can quickly get a list of skipped images during the vault.
There shd be some way to extract this list from the files in the
"/usr/openv/netbackup/vault/sessions/" directory. I could then probably
manually duplicate them.Any suggestions are welcome since I have run
out of ideas.Regards,PP BIJU KRISHNAN
