DAR – disk archive software

Last Updated on October 14, 2023

Disk ARchive (DAR) is a full featured archiver with support for differential backups, slices, compression, ATTR/ACL support. DAR also supports pipes for remote operations, including with ssh. It can remove files during restoration.

This application can store a backup in several files (called “slices” in the following) of a given size, eventually pausing or running a user command/script before starting the next slice.

There are graphical user interfaces available for DAR including KDar and DarGUI, although KDar is unmaintained.

Features include:

  • Directory tree snapshot recording the inode status of files.
  • Compression including:
    • Per-file compression with gzip or bzip2 (as opposed to compressing the whole archive).
  • Fast extraction of files.
  • Fast listing of archive files.
  • Strong Blowfish encryption.
  • Flat restoration.
  • Filters.
  • Support slices, archives split over multiple files of a particular size.
  • Direct Access – Dar first reads the catalogue (i.e. the contents of the backup), then it goes directly to the location of the saved file(s) you want to restore and proceed to restoration.
  • Full or differential backup.
  • Hard links.
  • Extended attributes.
  • Archive testing – detect data corruption in the archive.
  • Remote operations.
  • Isolation – the catalogue (i.e. the contents of an archive) can be extracted (this operation is called isolation) to a small file, that can in turn be used as reference for differential archive.
  • Re-shape slices of an existing archive.
  • Scrambling – the archive can be scrambled by using a pass phrase.
  • Data protection.
  • Archive merging – merge two existing archives into one archive.
  • Archive subsetting – define a subset of files from an archive and put them into a new archive without having to really extract these files to disk.
  • Cross-platform support – runs under Linux, FreeBSD, NetBSD, macOS, Solaris, and Windows.
