vsbackup.h contains the following programming interfaces:

Classes

IVssBackupComponents The IVssBackupComponents interface is used by a requester to poll writers about file status and to run backup/restore operations.
IVssBackupComponentsEx Provides methods for requesters to run backup and restore operations using multiple writer instances.
IVssBackupComponentsEx2 Defines additional methods that requesters can use to run backup and restore operations.
IVssBackupComponentsEx3 Defines additional methods that requesters can use to perform LUN resynchronization and return extended writer status information.
IVssBackupComponentsEx4 Defines additional methods to support the processing of UNC file share paths in a requester.
IVssExamineWriterMetadata The IVssExamineWriterMetadata interface is a C++ (not COM) interface that allows a requester to examine the metadata of a specific writer instance.
IVssExamineWriterMetadataEx Provides a method to retrieve the writer instance name and other basic information for a specific writer instance.
IVssExamineWriterMetadataEx2 Defines methods to retrieve version information and other basic information for a specific writer instance.
IVssWMComponent The IVssWMComponent is a C++ (not COM) interface that allows access to component information stored in a Writer Metadata Document.
IVssWriterComponentsExt The IVssWriterComponentsExt interface is a C++ (not COM) interface used by requesters to access and modify the components of a writer involved in a backup.

Functions

CreateVssBackupComponents The CreateVssBackupComponents function (vsbackup.h) creates an IVssBackupComponents interface object and returns a pointer to it.
CreateVssBackupComponentsInternal The CreateVssBackupComponents function (vsbackup.h) creates an IVssBackupComponents interface object and returns a pointer to it.
CreateVssExamineWriterMetadata The CreateVssExamineWriterMetadata function (vsbackup.h) creates an IVssExamineWriterMetadata object.
CreateVssExamineWriterMetadataInternal The CreateVssExamineWriterMetadata function (vsbackup.h) creates an IVssExamineWriterMetadata object.
IsVolumeSnapshotted The IsVolumeSnapshotted function (vsbackup.h) determines whether any shadow copies exist for the specified volume.
IsVolumeSnapshottedInternal The IsVolumeSnapshottedInternal function (vsbackup.h) determines whether any shadow copies exist for the specified volume.
ShouldBlockRevert Checks the registry for writers that should block revert operations on the specified volume.
VssFreeSnapshotProperties The VssFreeSnapshotProperties function (vsbackup.h) is used to free the contents of a VSS_SNAPSHOT_PROP structure as part of managing its life cycle.
VssFreeSnapshotPropertiesInternal The VssFreeSnapshotPropertiesInternal function (vsbackup.h) is used to free the contents of a VSS_SNAPSHOT_PROP structure as part of managing its life cycle.
