dump 0.4b47 Ext2/3/4 file system dump/restore utilities
Dump examines files in a file system, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. Subsequent incremental backups can then be layered on top of the full backup. The restore command performs the inverse function of dump; it can restore a full backup of a file system. Single files and directory subtrees may also be restored from full or partial backups in interactive mode.
