 You can use additional options to change VSS behaviour:
 
  * ``-o vss.timeout`` specifies timeout for VSS snapshot creation, the default value is 120 seconds
- * ``-o vss.excludeallmountpoints`` disable auto snapshotting of all volume mount points
- * ``-o vss.excludevolumes`` allows excluding specific volumes or volume mount points from snapshotting
