Re: [Veritas-bu] Slow backup speed
Did you restart the netbackup daemons/services after making the change? Do you still have the copy mounted? If so it may also be worth running a test using only 1 LTO-4 drive and see if the performance increases.

[Veritas-bu] Backup of SAP NetWeaver AS Java
Dear all, I have a problem in database backup of SAP NetWeaver 7.00 AS Java (Oracle DB). As i know, NetBackup (SAP Agent) uses BACKINT to connect to the SAP's BRBACKUP. Since our SAP NetWeaver is AS Java system (not ABAP system), therefore I can't execute the transaction code DB13 (which is available in SAP ABAP system) to trigger/initiate the backup event to start. So, my question is, how can I trigger/initiate the NetBackup SAP Agent / BACKINT to start the backup of Oracle DB in SAP NetWeaver 7.00 AS Java? Thank you in advance. -- Best Regards, Adrian Soetanto PT. Bentoel Prima - Infrastructure Staff Jl. Raya Karanglo - Singosari, Malang Tel.

Re: [Veritas-bu] Slow backup speed
Hemant, are you using FC or SATA drives on the 6140 S-vols? Also assuming this is virtualized behind the 9990V in order to use ShadowImage. I'd probably recommend some testing independent of NetBackup to see how fast you can pull data off these volumes. Such as use something like ufsdump, tar or cpio output to /dev/null and watch the transfer rates with something like iostat -xcn 3. If that looks good try manually allocating one of the LTO4 drives and check the raw write speeds to the tapes in a similar fashion. If both check out ok then it's most likely a NetBackup tuning issue. Either way, at least you'd know where the bottle-neck is at that point. Hope this helps.

[Veritas-bu] Off Topic: Quantum Library Support
Is anyone else having difficulty with Quantum backup/autoloader libraries, especially in the Asia / Pacific Rim markets? We've got a standard backup configuration that we deploy to our design centers and we've been having difficulties with the Quantum libraries we deploy as part of this configuration. In one case, I had a SuperLoader 3 go bad in March, replacement go bad in April, and the replacement replacement seems to be DOA. It takes Quantum 2 weeks to get me a replacement library and it's a roll of the dice getting the replacement unit to work. (This is their Rapid Exchange program.) It's been suggested that environmental factors in our design centers are causing the failures, but I'm of the opinion that Quantum's replacement quality is poor. We've had some library issues in the US and Europe as well, but nothing as bad as the issues I see in my Asia / Pacific Rim environments. We've already decided to modify our standard deployment template to replace the Quantum library with a similar Dell, but I've got something like 9 libraries already deployed. If I can't get to the bottom of my library issues, I'm going to be stuck with this nightmare until hardware refresh happens in 3 years. -Jonathan ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
Re: [Veritas-bu] Off Topic: Quantum Library Support
You might want to check on how similar that Dell is. Often same tape library is simply relabeled with another vendor's name. I don't think Dell is actually making any libraries itself. It would not be good if you shipped it only to find it is a Quantum OEM if the issue is with manufacturing and not support. It was amusing to me to work at 3 separate jobs. One had an STK L 700, Another had an HP which was actually the STK L 700 and yet another had a Sun (before they bought STK) which was also the same library. Of course the vendors always tell you they put something in the firmware that makes it so much better. -Original Message- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Martin, Jonathan Sent: Tuesday, May 11, 2010 10:14 AM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] Off Topic: Quantum Library Support Is anyone else having difficulty with Quantum backup/autoloader libraries, especially in the Asia / Pacific Rim markets?

Re: [Veritas-bu] Off Topic: Quantum Library Support
Yeah, when I said similar I meant that the Dell PV124t is a Quantum SuperLoader3 with a different faceplate and firmware. I don't actually have any complaints about the library itself, it works great for the 2-3TB we need to backup weekly. My concern is more related to the quality of service and replacement units when they do fail. -Jonathan -Original Message- From: Lightner, Jeff [mailto:jlight...@water.com] Sent: Tuesday, May 11, 2010 12:12 PM To: Martin, Jonathan; veritas-bu@mailman.eng.auburn.edu Subject: RE: [Veritas-bu] Off Topic: Quantum Library Support You might want to check on how similar that Dell is.

Re: [Veritas-bu] Scratch Media Netbackup 6.5.
Have your WORM policy write to a single volume pool. Then create a barcode rule that directs all WORM barcodes automatically into that volume pool when you load them. You can't really have a WORM scratch pool because then any job that wrote to any volume pool that needed a media would grab a WORM tape. -Jonathan From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Ulises Rodriguez Sent: Tuesday, May 11, 2010 4:17 PM To: 'veritas-bu@mailman.eng.auburn.edu' Subject: [Veritas-bu] Scratch Media Netbackup 6.5.
