Backup- \\SHEX\C:

  • I have had backups running successful for two weeks now and here are the last few things I did. I think it was the MinDiffAreaFileSize registry hack that "put it over the edge". But anyone reading please make sure your VSS has all the latest hotfixes and that you re-register the DLLs/reboot server.

    1) Make sure your disks have no errors. Run a checkdsk and any hardware specific utilities provided by vendor to ensure disk/array health. replace disks that return hard errors

    2) VSS Hotfixes: I believe http://support.microsoft.com/default.aspx?scid=kb;EN-US;940349 hotfix KB94039

    3) If you have all the latest VSS hotfixes, reregister your VSS files and reboot server:
    Suggestion 3: Reset VSS configuration
    -------------------------------------------------
    If this problem continues, please perform the following steps to reset VSS
    configuration:

    Go into control panel and reset the com configuration.

    a. In control panel click "add remove programs".
    b. Click "Add remove windows components".
    c. Click the "Next" button (windows will re-initialize the COM
    configuration).

    . Look in "Component Services" MMC and make sure that the MS Shadow Copy
    Provider does not show up as a COM+ application. The software provider
    should NOT show up in Component Services on Windows 2003 and above. If it
    is, you will have trouble initializing the VSS coordinator and provider
    instances.

    a. In the Component Services MMC, navigate to "Component Services\My
    Computer\COM+ Applications\"
    b. View the properties of the "MS Software Shadow Copy Provider" if it
    exists. In the "advanced" tab, uncheck the "Disable deletion" checkbox and
    then delete the "MS Software Shadow Copy Provider" from COM+ Applications.

    Run FIXVSS03.BAT to reset VSS configuration.

    rem FILENAME: FIXVSS03.BAT
    rem
    net stop "System Event Notification"
    net stop "COM+ Event System"
    net stop "Microsoft Software Shadow Copy Provider "
    net stop "Volume Shadow Copy"
    cd /d %windir%\system32
    net stop vss
    net stop swprv
    regsvr32 /s ole32.dll
    regsvr32 /s oleaut32.dll
    regsvr32 /s vss_ps.dll
    vssvc /register
    regsvr32 /s /i swprv.dll
    regsvr32 /s /i eventcls.dll
    regsvr32 /s es.dll
    regsvr32 /s stdprov.dll
    regsvr32 /s vssui.dll
    regsvr32 /s msxml.dll
    regsvr32 /s msxml3.dll
    regsvr32 /s msxml4.dll
    Cd /d %systemroot%\syswow64
    regsvr32 /s ole32.dll
    regsvr32 /s vss_ps.dll
    regsvr32 /s es.dll
    regsvr32 /s stdprov.dll
    regsvr32 /s msxml3.dll
    regsvr32 /s msxml.dll
    regsvr32 /s msxml4.dll
    net start "COM+ Event System"

    4. Disable VSS tracing if it is enabled.

    5. Configure MinDiffAreaFileSize registry key
    ----------------------------------------------------------------------
    This problem may occur when the shadow copy storage area is used up. Please
    ensure that you have installed the latest SBS updates; in addition, please
    perform the following steps to configure higher MinDiffAreaFileSize
    registry value.

    a. Click Start -> Run, type "regedit" in the text box, and press Enter.
    b. Locate the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VolSnap
    c. On the Edit menu, pointed to New, and then clicked DWORD value.
    d. Typed MinDiffAreaFileSize , and then pressed ENTER.
    e. On the Edit menu, clicked Modify.
    f. Changed the size to 3000 (decimal), and then click OK.
    g. Reboot the server to test this issue again.
