%1 %2 /Type=ShadowType /For=ForVolumeSpec      [/Provider=ProviderNameOrID] [/AutoRetry=MaxRetryMinutes]     - Creates a new shadow copy of the specified type for the ForVolumeSpec.       The default shadow copy Provider will be called unless ProviderNameOrID      is specified.  The ForVolumeSpec must be a local volume drive letter or     mount point.  If MaxRetryMinutes is specified and there is another      process creating a shadow copy, vssadmin will continue to try to create      the shadow copy for MaxRetryMinutes minutes.     - The provider ID can be obtained by using the List Providers command.     When entering a Provider ID, it must be in the following format:        {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}      where the X's are hexadecimal characters.
