Backing up Drive that's Volume Name (Guid) changes RRS feed

  • Question

  • Hi,

    We Used DPM 1807 to backup Data on Windows 10 Clients, but we faced an issue after format D drive on Windows Client, the format process change GUID for the Volume, so DPM was unable to detect the correct GUID, we use a workaround but for windows 7 to change GUID and match it with the old one that DPM needs in order to backup from registry but unfortunately this not help anymore to windows 10 

    any help plz

  • Hi,

    DPM uses the Volume GUID to recognize the volume, if a volume GUID is changed, DPM will consider this as a new volume.

    You could try using the Migrate-DataSource.ps1 script to re-associate the DPM replica to the new GUID.

    Best regards,

  • Check the syntax in the provided link.

    =================================================

    EXAMPLE
    =======
    The Bolded items are the user inputs.  


    PS C:\Program Files\Microsoft DPM\DPM\bin> migrate-datasource
    DPMServer: DPM01
      auto for AUTO SEARCH for matching volume letters
      manual for MANUAL INPUT of 'from' and 'to' Volumes, to be migrated
    option( auto or manual): manual
    PSName: FS01
    Domain: contoso.com
    Running inquiry on the PS

    List of fileSystem datasources under protection(candidates for migration):
    1 E:\   File Server FS01

    Number: 1
    The old datasource selected is : File Server FS01   E:\

    The following are the list of Datasourcevolumes available for protection, which would u like to consider:
    (Migration not allowed from normal volume to a mounted volume)
    1 C:\

    2 E:\

    Number: 2

    The New datasource selected is  E:\
    Confirm migration (Y/N)? : Y
    newDataSource= E:\ oldDataSource= E:\

    Migration Completed for newDataSource= E:\ oldDataSource= E:\
    Running inquiry on the PS for App restore

    Run Consistency check to make replica Valid

    PS C:\Program Files\Microsoft DPM\DPM\bin>
