IVssBackupComponents::GetSnapshotProperties method (vsbackup.h)
The GetSnapshotProperties method gets the properties of the specified shadow copy.
HRESULT GetSnapshotProperties( [in] VSS_ID SnapshotId, [out] VSS_SNAPSHOT_PROP *pProp );
The identifier of the shadow copy of a volume as returned by IVssBackupComponents::AddToSnapshotSet.
The address of a caller-allocated VSS_SNAPSHOT_PROP structure that receives the shadow copy properties. The software provider is responsible for setting the members of this structure. The software provider allocates memory for all string members that it sets in the structure. When the structure is no longer needed, the software provider is responsible for freeing these strings by calling the VssFreeSnapshotProperties function.
