The DFS Backup System can help you automate the process of making permanent copies of filesets on tape. You can create a full backup, which includes all of the data from every file in a fileset, or you can back up data incrementally, copying only those files that have changed since a previous dump. In the same fashion, you can restore filesets completely, or you can do an incremental, date-specific restore, which re-creates the filesets as they were before a specific date. Because both DCE LFS filesets and exported non-LFS file systems have entries in the Fileset Location Database (FLDB), the DFS Backup System can be used with both types of filesets.
This topic introduces the DFS Backup System. It describes configuration issues related to the performance of backup and restore operations. Backing Up and Restoring Data provides specific details about listing information from the Backup Database, backing up and restoring data, and administering the Backup Database. Refer to this topic for information about configuring the Backup System and preparing it for backing up and restoring data; refer to Backing Up and Restoring Data for information about backing up and restoring data.
