Once the DFS Backup System is properly configured, it can be used to help automate the process of making backup copies of both DCE LFS and non-LFS filesets on tape. These copies can then be used to restore data to the file system in the event of data loss. The Backup Database, which stores information about the dump schedule for backups, the locations of the Backup System's Tape Coordinators, the fileset families and their entries that can be dumped, and other administrative information, can also be backed up to tape and restored if the file system becomes damaged or corrupted.
This topic describes how to use the Backup System to list backup information, back up file system data, and restore data to the file system if necessary. It also details the operations involved in administering the Backup Database, and describes canceling operations from the interactive interface.
The operations in this topic assume that the Tape Coordinator machines are properly configured (including any special requirements for stackers, jukeboxes, or other automated devices), the fileset families and fileset entries are defined, the dump hierarchy is defined, and the required tapes are labeled, as necessary. Configuring the Backup System describes configuration of the Backup System in detail; make sure the Backup System is properly configured according to the guidelines detailed in Configuring the Backup System before attempting to use it to perform any of the operations described in this topic.
