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, ...)

    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.

    DAR can do everything you need, it is very well documented and supported.

    Hard to believe this got a negative review. Everything about DAR shows attention to detail. Each file is compressed inside the archive, reducing the chance of catastrophic corruption. Commands can be issued at intervals during archive creation - to burn split archives to DVD, for example. Encryption is supported. Another neat feature is the catalogue, which can be used as a reference point for differential network backups, thus reducing network traffic considerably. All in all an excellent piece of software, carefully maintained by a responsive developer. 5 stars.

    I've been using this for years with zero problems. From reading the mail list I can see support for those who have questions is superb.
