The VMware backup job failed to proceed with the error message "An error occurred while saving a snapshot: msg.snapshot.error-QUIESCINGERROR". I restarted the whole instance and checked in vSphere client during the backup schedule that the same error is shown while the VM snapshot is on progress. Please advise how to fix this issue as we need a valid backup data by end on this weekend.

@Patrick Please check whether the VM machine that you are trying to backup is windows 2008 R2 or windows server 2008 SP2 and update us.

@emmanuel Yes, The VM machine that we are trying to backup is windows server 2008 R2. Is that you are having any limitation in backing up these Os versions ?

The reported issue specifically affects Windows Server 2008 R2 and Windows Server 2008 SP2, where the Virtual Disk service does not start in the Windows guest operating system on the affected virtual machine. The same is addressed in VMware kb articles.

To resolve this issue, start the Windows Virtual Disk service by following the below steps:

  • Log in to the Windows operating system as an Administrator.
  • Click Start, type services.msc, and click Enter.
  • Right-click the Virtual Disk service and click Start.

Now try scheduling the problematic backup job and check whether the reported issue is fixed and update us.

You can determine whether the backup failure is due to Windows Virtual Disk service by checking the below symptoms.

  • we won't be able to create a quiesced snapshot of the problematic virtual machine.
  • The snapshot operation will fail approximately at 30%.
  • In the vSphere Client, you can find an error similar to the below error:

    An error occurred while saving the snapshot: msg.snapshot.error-QUIESCING-ERROR

  • You can see the following entries in the vmware.log file, located at /vmfs/volumes/datastore/Affected_VM/.

    The error message was: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.
