access denied to browse Non VSS Datasource Writer folder RRS feed

  • Question

  • Dear,

    I have two server DPM 2010 3.0.8185.0 installed on Windows 2008 R2.

    From DPM in the disaster recovery site (replica server) I can't browse system protection and BMR backup.

    From DPM console i viewe this path

    C:\Program Files\Microsoft DPM\DPM\Volumes\Replica\Non VSS Datasource Writer\vol_c41fd379-0cf8-4f50-b424-261c8d2e562f\c876fc69-991b-4fab-90ca-1d1ed465cec6\Full\C-Vol\

    I can browse inside "vol_c41..." until "WindowsImageBackup" but if I try to go inside windows tell me access denied i have no permission.

    I tried also "dpmbackup -replicas" and browse to "C:\Program Files\Microsoft DPM\DPM\Volumes\Shadow Copy\Non VSS Datasource Writer" but the problem is the same.

    I need to copy to a usb disk the system state and bmr backup, how can I do?

    Regards,

    Luca Passioni

  • Hi Luca,

    Could you try this :

    1) Download psexec.exe from www.sysinternals.com
    2) Run PSEXEC -s cmd.exe   (this will switch window to system context)
    3) Afterwards - type WHOAMI it should return: nt authority\system
    4)  Now CD to the replica volume under program files\Microsoft DPM\DPM\Volumes\Shadowcopy\...
    5)  Copy the BMR backup to a folder/network location

  • Hi Luca,

    You need to connect with local administrator account or disable "User Account control" (Restart need).

    Domain admin won't give you enought permission ^^

    For UAC => Control panel/System and security/Change User account control settings

    Then you will be able to browse DPM volumes and backup your data from C:\Program Files\Microsoft DPM\DPM\Volumes\Shadow Copy\Non VSS Datasource Writer" on USB disk.

  • Hi Stephane,

    Yes the UAC WAS already disabled.

    To be sure, I restart now the DPM Server but I continue to no access to folder.

    I remember You that in the "Non VSS DataSource folder" there is a  system protection+bmr from a secondary dpm server.

  • Hi Luca,

    When you use DPMbackup.exe -replicas to expose your replica, your data are in "C:\Program files\Microsoft DPM\DPM\Volumes\ShadowCopy" folder.

    Edit: I made a test and I have the same behaviour... I will try to understand why :)

    Edit2: When trying to take ownership of WindowsImageBackup through advanced Security Setting , I get "unable to set new owner on WindowsImageBackup - The media is write protected". All others Exposed replica are fine. It's seems that there is some security settings that prevent WindowsImageBackup to be modified on DPm server ?

    Stephane.
