Description

DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing.

DAR knows how to perform full, differential, incremental and decremental backups. It provides testing, diffing, merging, listing and of course data extracting from existing archives.

Archive internal's catalog, allows very quick restoration of a even a single file from a very large, eventually sliced, compressed and encrypted archive.

Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes), it has support for ssh and is suitable for tapes and disks (floppy, CD, DVD, hard disks, ...)

    Excellent and powerful tool, especially when combined with various user-submitted additional scripts. Many options can be confusing but simple backups and restores work well, and the options really prove themselves when you need them! Maintainer is active on support mailing lists.

    I find dar very useful. I have created a config file in which I put some comments so I know the meaning of the individual options. This way i can adjust dar to all my needs. I'm pretty sure that no GUI-programm has this variety of options. The program works flawlessly. The regular backups on external USB-disks start by calling up a self written bash skript which is easy to do and allows me to choose easily between incremental and full backup. I gave an "Excellent" to the Design, because the flexibility of the command line cannot be matched by any GUI-program. The man pages are well written, other info is available in the net, and there is a user mailing list.

    Take your time to learn it, make your scripts for backup, and let it live on its own - it pays back to learn.

    I use this great tool now for over ten years and you can do the simple things like full backups very easily but you also have the capability to also do more sophisticated things like incremental/differential backups. And when your full backups start to eat up your space you can even also retrospectively shrink the older backups to become differential ones in comparison to the newer ones - removing files which have not changed over time. And the dar_manager - if regularly used to maintain your archives - is a big plus if you need to find any previous version of a file.
