E (Volume Shadow Copy Service)
explicit component inclusion
Adding of a component's information to a requester's Backup Components Document when it participates in a backup or restore operation. Requesters use IVssBackupComponents::AddComponent to explicitly include a component in a backup operation, and IVssBackupComponents::SetSelectedForRestore or IVssBackupComponents::AddRestoreSubcomponent to explicitly include a component in a restore operation.
If any component of a writer is backed up or restored, all nonselectable components without any selectable ancestors must be explicitly included in a backup or restore operation.
Selectable components without selectable ancestors chosen by a requester for participation in a backup or restore must be explicitly included in the operation.
Nonselectable components with a selectable ancestor are never explicitly included.
Selectable components with a selectable ancestor may be included explicitly, or may be included implicitly if the ancestor is included explicitly.
exposed shadow copy
A volume shadow copy that is mounted on a system and available to processes other than the one that manages it. A shadow copy volume mounted under a drive letter or a directory location is referred to as "locally exposed." A shadow copy volume accessible through a share (except for client-accessible shadow copies) is referred to as "remotely exposed." All exposed shadow copies are also surfaced shadow copies. See also client accessible shadow copy, shadow copy.
