- certification authority
An entity entrusted to issue certificates asserting that the recipient individual, machine, or organization requesting the certificate fulfills the conditions of an established policy.
- client-accessible shadow copy
A shadow copy created by the system provider to support Shadow Copies for Shared Folders and other rollback mechanisms, which allow clients to see old versions of files and undo mistakes without requiring a full restore. A client-accessible shadow copy is created using the VSS_CTX_CLIENT_ACCESSIBLE value of the _VSS_SNAPSHOT_CONTEXT enumeration. In addition, the VSS_VOLSNAP_ATTR_CLIENT_ACCESSIBLE value of the _VSS_VOLUME_SNAPSHOT_ATTRIBUTES enumeration is set automatically for client-accessible shadow copies. See also Shadow Copies for Shared Folders.
- component dependency
A situation in which a component (and the component set it defines) managed by one writer cannot be backed up or restore independently of components managed by others writers. A dependency does not indicate an order of preference between the component with the documented dependencies and the components it depends on: a dependency merely indicates that the component and the components it depends on must always be backed up or restored together.
- component mode
A mode in which a backup or restore operation makes use of a writer's component information. See also selectable component.
- component set
A group of components with at least one selectable (for either backup or restore) component and a number of nonselectable components organized in a hierarchy by their logical paths. The implicit participation in a backup or restore operation depends on the explicit inclusion of the top-level selectable component. Only the component information of this selectable component is included in the Backup Components Document. A component set may include selectable and nonselectable subcomponents. See also logical path, selectable component.
- copy-on-write shadow copy
A shadow copy created by saving only the differences from the original volume.
- crash consistent state
The state of disks equivalent to what would be found following a catastrophic failure that abruptly shuts down the system. A restore from such a shadow copy set would be equivalent to a reboot following an abrupt shutdown. This is the default state of data that has been shadow copied without the support of writers.
