How to copy a volume from primary DPM to secondary DPM RRS feed

  • Question

  • We had a disk failure in the secondary DPM's disk array and one large volume that holds a file server drive became corrupt. We had to delete the volume and re-create it at the secondary DPM PG.

    Is there a way we can copy or transfer the data for that lost volume from the primary DPM to secondary DPM other than syncing?

    It's a 400GB data and it would take days to synch, plust I would like to keep the same restore points we have in the primary DPM server after we transfer the data. 

    Thanks in advance.

  • You can copy the data from the primary's replica folder to the secondary's replica folder manually and then perform a consistency check. When you create the secondary protection you can choose to sync the replica volume manually. You then need to copy the data from the c:\program files\microsoft dpm\dpm\volumes\replica\data source of the server you are protecting to a portable device and then connect that portable device to the secondary and copy to the same path on the secondary that will have been created when you set up the protection group (look out for UAC if you are using a non administrator account as you'll hit permission issues). Keep in mind that the data paths need to be the same in the replica folder on the secondary as they are on the primary.

    You will then need to run a consistency check on the secondary to create the initial block map, which shouldn't transfer too much data but may take some time dependent on the number of items being protected.

    From that point on it's business as usual.

  • Primary DPM is Windows 2003 R2 and secondary DPM is 2008 R2, both running DPM 2007.
