You can set a virtual disk to independent mode to exclude the disk from any snapshots taken of its virtual machine.

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.

Required privileges:

Virtual machine.State.Remove Snapshot

Virtual machine.Configuration.Modify device settings


Select Inventory > Virtual Machine > Edit Settings.


Click the Hardware tab and select the hard disk to exclude.


Under Mode, select Independent.

Snapshots do not affect the state of an independent disk.


Any disk, regardless of its type, that is created after you take a snapshot does not appear if you revert to that snapshot.


Select an independent disk mode option.



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.
