Dar is a shell command that makes backup of a directory tree and files. Its features include splitting archives over several files, DVD, CD, ZIP, or floppies, compression, full or differential backups, strong encryption, proper saving and restoration of hard links, extended attributes, file forks, Door inodes, and sparse files, remote backup using pipes and external commands (such as ssh), and rearrangement of the "slices" of an existing archive. It can run commands between slices, before and after saving some defined files or directories (for a proper database backup, for example), and quickly retrieve individual files from differential and full backups. Several external GUIs exist as alternatives to its CLI interface, like kdar, DarGUI, SaraB, etc.

标签: major release
This release closes a development cycle of 5 years, with almost 6 months of intensive testing. There more than 50 new features and improvements, including the sequential reading mode that makes dar suitable for tapes, new ciphers, and compression algorithms, generation of an MD5/SHA-1 hashing file for each archive slice, sparse file handling, the ability to launch a user-defined command before and after saving some particular files or directories (to be able to back up a live database properly, for example) and many other features.

标签: Minor Release
This is a maintenance release that fixes a few bugs. The code removing slices of an old archive was fixed. The libdar was improved to be more robust when reading a very corrupted archive, which would otherwise lead dar in an endless loop. Several occurrences of double memory release were fixed.

标签: Minor bugfixes
Fixes include corrupted archive generation in some rare and random cases when using Blowfish strong encryption (this type of corruption can be detected by testing your archive with dar). There is no security issue here. Some minor speed optimizations are also included.
