The file that contains full and incremental back-up information for use with the dump/restore utility is /etc/dumpdates.
Dump examines files in a filesystem, 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 filesystem. Single files and directory subtrees may also be restored from full or partial backups in interactive mode.
