Re: [Veritas-bu] how to copy backups from data domaintotapew/netbackup 6.5
If you ask me, you should be considering the OST interface, not the VTL interface. It will give you a bigger boost in performance than the VTL interface will, from what they've been publishing lately. In addition, in a few months, OST will support copying to tape via OST. You'll get better performance to start, then get more functionality once that's available. _ From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Hickman, Tony Sent: Monday, March 09, 2009 12:16 PM To: Jeff Lightner; Donaldson, Mark; veritas-bu@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] how to copy backups from data domaintotapew/netbackup 6.5 Thanks for the many replies, and my apologies for taking awhile to respond. I just got off of a very long support call with Data Domain and I mentioned the tape backups to the tech I was working with. The Data Domain device is setup as a disk storage unit. It has VTL capabilities but the VTL has not been setup yet. The tech recommended that we setup VTL but wanted me to check with our assigned systems engineer before proceeding. We have one Win 2003 server as our master server, and we have a Quantum Scalar i500 that holds our tapes. Before the Data Domain everything was going to tape. I am not certain just yet if the VTL setup is required to copy to the tapes or not, or if I can just script something out and go? It is becoming increasingly critical for me to find a way to get the backups off of the Data Domain and get them to tape. Currently our retention periods are set at 3 months for all backups. Our corporate policy states we must take the quarterly fulls to tape and archive them offsite. The problem is that we have yet to grab our 4th quarter tape backups for 2008 and we are getting closer to running out of time. Also the Data Domain is nearing it's maximum capacity. So the plan is to get the 08 4th quarter fulls off to tape and then drop our retention periods down to 1 month from 3 month to help free up space. I will do some research here shortly about the bpduplicate command and see what I can come up with. I'm not that great at scripting but I can normally find my way around.

This list was recommended to me by someone and here I am. Here is my current dilemma: We went to using a Data Domain device along with NetBackup 6.5 in late December. We do not have the Vault add-on for NetBackup. Currently all of our backups are going to the Data Domain. Our corporate policy requires us to make quarterly full backups to tape. I am trying to figure out how I can copy backups off of the Data Domain to a tape library

I use DSU with the disk staging schedule configured, Basic Disk is no charge. it works quite well for me with all automated duplication from the disk to tapes. On Mon, Mar 9, 2009 at 6:21 PM, W.
