Create a Temporary Snapshot on the Target Virtual Machine

The low-level procedure for creating a snapshot of a virtual machine is documented in the section Creating a Snapshot. Set the quiesce flag True to make the file system quiescent, otherwise the snapshot might represent a transitional system state, with inconsistent data. Restoring such data might be destructive.

Another flag named memory allows you to include in the snapshot a dump of the powered on virtual machine's in-memory state. This is not needed for backup, so set this flag to False.
