  • In this case, we can check if any third party shadow copy provider is present on machine. If yes, then we can try to disable or remove it. This can be done as given below:

    1. Browse to registry location "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS" and  take the backup of VV key

    2. Under this key, we can see two providers : Microsoft and another should be third party

    3. Third party provider's GUID can be confirmed in command "vssadmin list providers"

    Reboot the machine and run backup ... it should be fine.

  • having followed the articles, and checked the registry ( only the one provider listed )

    still seeing same errors Backup Status

    Operation: Backup

    Active backup destination: 4mm DDS

    Media name: "Media created 09/08/2012 at 09:41"

    Volume shadow copy creation: Attempt 1.

    Timeout before function completed

    Error returned while creating the volume shadow copy:0xffffffff.

    Error returned while creating the volume shadow copy:ffffffff

    Aborting Backup.

    but no VSS errors in the eventlog

    event ID 8019, backup failed is the only logged error

    any ideas?
