extracting files from shadow copy created by dpmbackup.exe RRS feed

  • Question

  • I can successfully run dpmbackup.exe -replicas from a command prompt. A folder structure like this is created:

    C:\Program Files\Microsoft System Center 2012\DPM\DPM\Volumes\ShadowCopy\File System

    |_____vol_78c204a2-d5bb-4abd-bc8f-7485f9cd7bfc

    ..........|______{355a2adb-7611-4528-b94b-4b4a8c07fc83}checkpoint

    ..........|______355a2adb-7611-4528-b94b-4b4a8c07fc83

    ......................|______DatasetContextInformation.xml

    ......................|______DatasourceProtectionIntent.xml

    ......................|______DatasourceVolumeMapping.xml

    In Windows Explorer that folder that begins with "vol_" shows a file size of one terrabyte. If I drill down to the subfolders, however, no further data is displayed and all I get are some small .xml files - how do I access all that data in the shadow copy? I did try opening disk manager, which showed the dpm_vol as not having a drive letter - I tried assigning a drive letter which succeeded, but, when I opened the drive, I got the same folder structure as above...

    I raised this question in a previous thread with a slightly different subject, but, the thread has died.

  • Mike: That worked with one caveat. It was trying to pull all sorts of stuff out of the recycle bin and encountered files that were listed as in the bin, but that it couldn't find. By adding the "/c" switch, I could get past that because that tells it to keep going if it encounters errors. So, the final command looks like this:
    xcopy *.* /s/h/c e:\dailybackup

  • Can anyone tell me if they are successfully using dpmbackup.exe -replicas to create shadow copies?

    If you are, could you just describe the folder structure you get, and how you're viewing it?

  • Hi,

    It could be that the subfolders are hidden, try doing a DIR /A /S to see the entire tree, then CD to the hidden folder(s)

  • Mike: Thank you for that reply - I had not been getting replies for awhile so I'd stopped checking. Running that command does indeed expose the underlying hidden folders. I tried using xcopy /s/h to copy those files and folders to regular physical hard drive, but I got the same results as before, with only four small files (three .xml files and a "checkpoint" file) being copied over. Any suggestion on how I can copy those hidden folders to my hard drive?

  • Hi,

    xcopy *.* /s /h x:\  should work.
