UFS

=Introduction= UFS (the Unix File System) is a filesystem commonly used on Unix systems in the 1980's and 1990's. It was originally developed for BSD Unix under the name Fast File System (FFS), and later adopted by AT&T for System V Release 4 (SVR4). A later improved version was UFS2.

Backups may be done with the ufsdump archiver (known simply as dump on older systems).
