Package dump: Information

The dump package contains both dump and restore. 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. The restore command performs
the inverse function of dump; it can restore a full backup of a filesystem.
Subsequent incremental backups can then be layered on top of the full backup.
Single files and directory subtrees may also be restored from full or partial
backups.
