DAR is able to make differential backups, split them over a set of disks or files of a given size, use compression, filter files or subtrees to be saved or not saved, directly access and restore given files. DAR is also able to handle extented attributes, and can make remote backups through an ssh session for example. Finally, DAR handles save and restore of hard and symbolic links.
