DPM 2010 raw attached storage upgrade RRS feed

  • Question

  • Hi Everyone

    I am about to change out my 7TB HP MSA60 for a 24TB SAS storage array. My question is how can I do this without losing my on disk backups.

    I have ~6TB of replicas on disk and I would very much like retain these. I can connect both storage arrays symaltaniously.

    Was wondering if there is some option to migrate the replicas?

    Thank you

  • Hi,

    See this technet article


    Using MigrateDatasourceDataFromDPM
    http://technet.microsoft.com/en-us/library/dd282970.aspx

    To make things easier, The following commands can be used with the ntdisk number as seen in either the get-DPMDISK output, the Windows Disk Management GUI or DPM Management - Disks GUI.

    EXAMPLE-1 These commands show the migrations going from NTDisk 1 to NTDisks 3, 5, 6.

    $source = get-dpmdisk -dpmserver DPM-SVR-NAME | where {$_.ntdiskid -eq 1}
    $destination = get-dpmdisk -dpmserver DPM-SVR-NAME | where {3,5,6 -contains $_.ntdiskid}
    MigrateDatasourceDataFromDPM.ps1 -DPMServername DPM-SVR-NAME -source $source -destination $destination

    EXAMPLE-2 These commands show the migrations going from NTDisk 1,2,3 to NTDisks 4,5,6.

    $source = get-dpmdisk -dpmserver DPM-SVR-NAME | where {1,2,3 -contains $_.ntdiskid}
    $destination = get-dpmdisk -dpmserver DPM-SVR-NAME | where {4,5,6 -contains $_.ntdiskid}
    MigrateDatasourceDataFromDPM.ps1 -DPMServername DPM-SVR-NAME -source $source -destination $destination
