DAR

DAR is the definitive backup solution for UNIX/Linux systems where data integrity is paramount. It goes beyond simple file copying by meticulously preserving every detail: all inode types, hard links, sparse files, Extended Attributes (such as Linux ACLs and SELinux tags), and filesystem-specific attributes (ext2/3/4, HFS+). This ensures a perfect, bit-for-bit restore. Archives are efficient thanks to selective compression and can be secured with strong encryption. DAR supports slicing archives, differential backups with binary delta, and remote transfer via FTP/SFTP. The internal catalog enables quick retrieval of any file from a massive, remote archive, making complex restores simple and fast.
