DAR (Disk Archiver)

DAR (Disk ARchive) is an archiving tool and a replacement for tar.

It features:

Support for slices, archives split over multiple files of a particular size.
Option of deleting files from the system which are removed in the archive.
Incremental backup.
Per-file compression with gzip or bzip2 (as opposed to compressing the whole archive). An individual can choose not to compress already compressed files based on their filename suffix as well.
Fast-extracting of files from anywhere in the archive.
Fast listing of archive contents through saving the catalogue of files in the archive.
Optional Blowfish encryption.

[edit] Frontends

There are GUI frontends for DAR called Kdar or DarGUI.

A scheduler/frontend known as SaraB allows the Towers of Hanoi, Grandfather-Father-Son, or any custom backup rotation strategy, and modifications are available for PAR file support. Extended versions known as bzSaraB and baras are also available.
