Check tape integrity RRS feed

  • Question

  • When I create tape backups I select "Check backup for data integrity". Sometimes, I would also like to check tape backups for integrity when they are returned from offsite storage. Is it possible to do this without changing the way my protection groups are checking for data integrity at the time of the backup? Is there a DPM management shell command to check the integrity of a particular tape?

  • Hello,

     

    yes, we do have a powershell command to verify a recovery point on tape.

     

    PS C:\Program Files\Microsoft DPM\DPM\bin> get-help Test-DPMTapeData -examples

    NAME
        Test-DPMTapeData

    SYNOPSIS
        Verifies the data set for a recovery point.

        EXAMPLE 1

        $pg = Get-ProtectionGroup -DPMServerName TestingServer
        $ds = Get-Datasource -ProtectionGroup $pg
        $rp = Get-RecoveryPoint -Datasource $ds
        $rsl = Get-RecoveryPointLocation -RecoveryPoint $rp[1]
        Test-DPMTapeData -RecoveryPoint $rp[1] -RecoveryPointLocation $rsl


        This command verifies the recovery point at the specified location.

  • Hi,

     

    Also, you can do this from the DPM recovery tab.  Both methods / Steps are outlined in this technet article:

    How to Verify Data on Tape: http://technet.microsoft.com/en-us/library/ff399285.aspx

     

    Cheers.
