  • Hi,

    The user has two choices when restoring files.

    A) He can see if a local shadow copy has what he needs.  Simply right-click a file or folder - look at properties, the previous versions tab.  If the range of local shadow copies has what he needs, simply restore from there and the local shadow copy will be used and no need to reach the DPM server.   This is simply a feature of the local operating system and DPM is in no way involved, we're just using built-in VSS snapshots and using previous versions tab to restore a file or directory.

    B) The local shadow copies do not have the file that needs restored, so he uses the DPM client to show all recovery points on the DPM Server.  Once he finds the recovery point, he clicks on it and DPM will make it available VIA a network share for him to select the files he wants to restore and he can copy them back to the local machine.    The user can do this from ANY client machine that has a DPM agent installed on it.  So if his laptop is lost or malfunctions and he gets a new laptop, he can restore all his data to the new machine from the DPM server once a DPM agent in installed on the new laptop and added to protection.

    lastly, the DPM administrator can restore files from the DPM console by selecting a recovery point under the recovery tab and restore back to the same machine, or to an alternate location (Any machine that has a DPM agent installed on it that the DPM server is protecting) for the user to gain access to the restored files.

  • Hi,

    Since DPM is not in total control of when a client synchronizes it's changed data with the DPM server, the recovery point time shown under the recovery tab will be the last time the client had a successful sync before the scheduled recovery point time on the DPM Server.  This more accurately represents the actual state of the data on the replica volume at the time of the recovery point.   Since clients can disconnect and reconnect at any time, they will synchronize on their own schedule.  The shadow copies are taken at the 8:00 12:00 and 18:00 hours on both the client (for previous versions locally) and on the DPM server for the recovery points.

  • Hi,

  • Hi,

    Synchronization times have no effect on shadow copy times.  Shadow copies occur on a scheduled basis (The times you have set for the protection group)

  • Hi,

    Sorry for delay, I was on vacation.

    Synchronizations simply transfer changed data from client to DPM server and apply the changes to the replica volume.  That occurs throughout the day.  However, none of that transferred dats is recoverable until after a snapshot is taken.  Once the snapshot is taken it's now a restore point that can be mounted and restored from under the recovery tab.   The VSS shadow copies maintain previous views of the replica volume, and is the basis of all recovery points.

  • So, if the client calls a restore, it will take the local VSS Shadow Copie, and there is no communication between Server and Client?

    If the Admin want to restore Date from the Client on the DPM Server, it will take the latest recovery point on the DPM Server?

    Hope this is correct.



    regards Michael
