back-end level applications

Indicates the point at which a writer is notified of a freeze by VSS. Writers that are initialized as back-end level applications are notified after writers initialized as front-end level applications and prior to those initialized as system-level applications. See also application level, front-end level applications, system-level applications, writer.

BackupComplete event

A VSS event indicating that a VSS backup has completed. This event should be followed by a BackupShutdown event under normal operation. See also BackupShutdown event.

Backup Components Document

An XML document created by a requester (using the IVssBackupComponents interface) in the course of setting up a restore or backup operation. The Backup Components Document contains a list of those explicitly included components, from one or more writers, participating in a backup or restore operation. It does not contain implicitly included component information. In contrast, a Writer Metadata Document contains only writer components that may participate in a backup.

A Backup Components Document can be saved to disk. See also explicit component inclusion, implicit component inclusion.

backup set

Those files to be backed up. It includes files selected by inclusion in a component, those indicated by writer-level include statements, less those files that have been explicitly included.

BackupShutdown event

A VSS event indicating that a compliant backup application has shut down. Normally, this is preceded by a BackupComplete event. However, if a backup terminates unexpectedly, this event can be generated without a preceding BackupComplete event. See also BackupComplete event.

backup stamp

A string containing information as to when a backup took place. VSS places no restriction on the format of this string, except that it be intelligible to all the writer instances of a given class. It may contain time and date information, logical sequence numbers, or any other information that will allow a writer of the same class to determine when the last backup has take place.
