Defines methods that allow applications to use the shadow copy protection feature of VSS.

To obtain an instance of the IVssDifferentialSoftwareSnapshotMgmt3 interface, call the QueryInterface method of the IVssDifferentialSoftwareSnapshotMgmt interface and pass the IID_IVssDifferentialSoftwareSnapshotMgmt3 constant as the interface identifier (IID) parameter.

Methods

The IVssDifferentialSoftwareSnapshotMgmt3 interface inherits from IVssDifferentialSoftwareSnapshotMgmt2 and IVssDifferentialSoftwareSnapshotMgmt.

In addition, IVssDifferentialSoftwareSnapshotMgmt3 defines the following methods.

Remarks

An application with administrator privilege can use the SetVolumeProtectLevel method to specify a shadow copy protection level for a volume and its shadow copy storage area. The possible protection levels are defined by the VSS_PROTECTION_LEVEL enumeration.

When a volume protection fault occurs, the application must call the GetVolumeProtectLevel method for the volume to identify the cause of the fault.
