DPM 2012 snapshot backup to tape from EMC SAN without D2D RRS feed

  • Question

  • Hi Team, is it possible to configure DPM2012 run D2D backup but only provide the snapshots to EMC SAN storage and use symantec netbackup to backup the snapshot direclty to tape without  going through the full D2D process? so we can save the space on SAN a lot as DPM uses too much space. Thanks!

  • Hi,

    It sounds like you want symantec to backup from a SAN snapshot of the protected server, so don't understand where DPM comes in.  Please clarify the senario.

  • thanks. the DPM does D2D job and backup the snapshots and recovery points to EMC SAN. Then netbackup take thoese snapshots and backup it tape as D2T process. Will this work? Thanks

  • HI,

    OK, So you want to reduce the D2D backup storage needs and let netbackup backup the replica data on DPM server.


    If you don't want to use DPM Disk to Disk to Tape (D2D2T) solution and instead want to utilize a 3rd party backup product for long term offsite tape backups - Using 3rd party to backup a DPM server is described here:   http://technet.microsoft.com/en-us/library/bb809019.aspx

    However, restores of protected data will need to be performed to an alternate location (Not back to the DPM server) by the 3rd party application.

    What I mean by this is the 3rd party backup application will be protecting the DPM replica volumes (either directly, or via a snapshot using dpmbackup –replicas) – and if a restore is required of a data that is older than what DPM has on disk, then the restore from tape will need to restore the files to an alternate location – anywhere but the DPM replica, as that will compromise current DPM disk based backups.   Restores from tape should be RARE if they have adequate retention range on DPM disk.
