dump | 4.4bsd dump and restore for ext2 filesystems | Mehr ...
Dump examines files on a filesystem and determines which files need to be backed up. These files are copied to the given disk, tape or other storage medium for safe keeping. . The restore command performs the inverse function of dump. A full backup of a file system may be restored and subsequent incremental backups layered on top of it. Single files and directory subtrees may be restored from full or partial backups.
