database component

A group of files used by a database and defined by a writer as needing to be handled as a unit during backup and restore operations. See also component, file group component.

default provider

See system provider.

deleted shadow copy

Deleted shadow copies are not accessible at all and must not be made accessible at any time in the future.

dependency

See component dependency.

device object

A string indicating the "root" of a shadow copied volume. Files and directories on a shadow copied volume can be referenced by prepending the device object string to a corresponding path on the original volume. As obtained as the m_pwszSnapshotDeviceObject member of the VSS_SNAPSHOT_PROP structure, the device object has no backslash ("\").

diff area

The location on the volume where the differential data is stored. This is also known as shadow copy storage space.

differenced files

Files involved in an incremental or differential backup operation implemented by updating entire files (as opposed to modifying sections of those files using partial file support). For instance, if to implement a differential backup an entire file (instead of just the modified section) is copied to a backup media, that file is a differenced file. See also incremental backup operations, differential backup operations, partial file support.

differential backup operations

A backup or restore operation performed only on files created or changed since the last full backup was saved. See also incremental backup operations, partial file support, differenced files.

differential data

Data that can be applied to an original volume to generate a shadow copy volume. This is also commonly known as copy-on-write data, but this documentation uses the term differential data.

directed targeting

A restoration mode by which a writer indicates that when a file is to be restored, it (the source file) should be remapped. The file may be restored to a new restore location and/or ranges of its data restored to different offset with the restore location.
