You can set a virtual disk to independent mode to exclude the disk from any snapshots taken of its virtual machine.
Prerequisites
Power off the virtual machine and delete any existing snapshots before you change the disk mode. Deleting a snapshot involves committing the existing data on the snapshot disk to the parent disk.

Independent - Persistent
|
Disks in persistent mode behave like
conventional disks on your physical computer. All data written to a disk in
persistent mode are written permanently to the disk.
|
|
Independent - Nonpersistent
|
Changes to disks in nonpersistent mode are
discarded when you power off or reset the virtual machine. With
nonpersistent mode, you can restart the virtual machine with a virtual disk in the same
state every time. Changes to the disk are written to and read from a redo
log file that is deleted when you power off or reset.
