Actually, TOP said he had backed up to an EDL/3DL (EMC Quantum box).
Jeff (Kaplan), Is it possible to use tape shadowing on the replicated system, so that the backup to one virtual tape, replicate to another virtual tape, then eject that virtual tape to create a physical tape? _____ From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Jeff Lightner Sent: Tuesday, March 17, 2009 7:34 AM To: Wilcox, Donald A (GE, Research); jeff kaplan; veritas-bu@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] dedup/replication Of course. Deduplicated information is only that information that is not already duplicated somewhere else on the storage device. Once you copy the image using bpduplicate to a tape there is no other copy of the information (so far as the tape is concerned) so obviously it would create a whole backup using duplicated and non-duplicated information from the Data Domain to create it. However, I didn't see anything by OP that suggested he was looking to save deduped information to a tape. I read his post as meaning: "There is a backup that went to Data Domain - we would now like to have a tape copy of the backup." The only real trick in what he wrote is how to get the information from the remote Data Domain to the local one. Since we don't do the remote setup here (we use vaulting to duplicate the local one to tape) I don't know exactly how that mechanism works. It may be automatic simply by requesting a bpduplicate of the image or it may require some step on the Data Domain itself. I feel confident however that there is a way to get the data from remote to onsite. Otherwise having a remote unit would be worse than useless. _____ From: Wilcox, Donald A (GE, Research) [mailto:wil...@ge.com] Sent: Tuesday, March 17, 2009 10:19 AM To: Jeff Lightner; jeff kaplan; veritas-bu@mailman.eng.auburn.edu Subject: RE: [Veritas-bu] dedup/replication It is my understanding that Data Domain deduplicated images get blown back up before going to tape, thereby losing the deduplication.

We have a local EDL/3DL replicating (de-duped data) to a remote EDL/3DL. We need to get a physical tape from the remote copy, but it has to NBU-aware.
