Properties

deltaDiskBackingsSupported | xsd:boolean | Flag indicating whether explicitly creating arbirary configurations of delta disk backings is supported. A delta disk backing is a way to preserve a virtual disk backing at some point in time. A delta disk backing is a file backing which in turn points to the original virtual disk backing (the parent). After a delta disk backing is added, all writes go to the delta disk backing. All reads first try the delta disk backing and then try the parent backing if needed. If this property is false, then delta disk backings can only be implicitly created through using snapshot operations and two virtual machines cannot safely share a parent disk backing. If this property is true, then delta disk backings can be explicitly created and managed, and two virtual machines may safely share a parent disk backing. In the context above, "safely" means that performing operations on one of the virtual machines will not affect the operation of the other virtual machine.

Since this property is on a DataObject, an update returned by WaitForUpdatesEx may contain values for this property when some other property on the DataObject changes.
