| ### Backing Up Filesets The system administrator uses the Backup System provided by DFS to make backup tape copies of filesets. For a discussion of how often to perform backups using bak commands, which filesets need to be backed up, and when to make full or incremental backups, see the OSF DCE DFS Administration Guide and Reference . The OSF DCE DFS Administration Guide and Reference also describes the following tasks: · Configuring a backup machine · Installing tape coordinators · Listing information from the backup database · Creating and reading tape labels · Performing a backup · Performing a restore · Canceling backup and restore operations ###
