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.

Release Notes: This release fixes a bug in the cache layer, used to reduce context switches when using Dar over SSH. This cache layer could grow continuously, leading dar/libdar using up half of the RAM depending on the operating system. Some minor typos and display bugs have also been fixed, and the configure script was adapted to better integrate with FreeBSD systems.
Release Notes: This release fixes compilation issues under Mac OS X and other FreeBSD systems using clang as a C++ compiler, brings some new libdar API calls, adds support for backslashes in DCF files, and fixes several minor bugs in the code and documentation.
Release Notes: This release adds several minor bugfixes, including one for a bug met under a very rare condition leading dar to wrongly report a file as corrupted at reading time, another for a bug in the sparse file detection mechanism which could lead dar to miss detecting small holes in files, several code updates to support compilation in g++11 mode, and other fixes relative to dar compilation within a BSD system like Mac OS X.
Release Notes: dar now takes care of umask when creating a slice when dar is used with the --hash option. This release also improves performance when used over ssh using dar_slave and provides fixes for several minor bugs and corrects spelling in documentation.
Release Notes: This release mainly contains two fixes. The first bug was located in the sparse file detection mechanism, leading a file containing a very specific string just before a hole to fail being backed up, with dar reporting "CRC error" at testing time. This same bug also caused "CRC error" to be reported at archive merging time. The second was located in the dar_manager database code, which led to database corruption. The fix avoids further corruption and also cleans up existing databases which have been corrupted by that bug.
