System and user data can be backed up to tape and restored as necessary. As mentioned previously, the DFS Backup System enables data from filesets to be backed up to tape. In the event of disk corruption or similar problems, the data can be restored from tape to the file system.
In addition, backup versions of DCE LFS filesets can be created and made available via users' directories for access by users if they mistakenly lose data. This allows users to access prior versions of their files easily, without burdening system administrators with requests for assistance. The administrators are then free to focus on more critical duties.
