What is BAR?

Features

• can store and restore files and images

• can split archive files into pieces; each piece can be read independent

• compress of data with zlib, bzip2 or lzma algorithms

• encryption with gcrypt algorithms (AES, TWOFISH etc.)

• asymmetric encryption with RSA

• fast file format: can find and extract single files without decompressing/decryption of the whole archive

• direct copy of archives to remote computer via FTP or SSH (SCP or SFTP)

• can store archives on CD/DVD (with external tools)

• support pre- and post-processing of CD/DVD images (e. g. for including functions of dvdisaster)

• daemon-mode with control over plain and TLS network connection

• integrated scheduler to start backups daily or weekly

• nice graphical front end (written in Java with SWT)

Requirements

• Unix system

• PTHREADs library (mandatory)

• zlib library (mandatory)

• bzib2 library (optional)

• xz utils (optional)

• gcrypt library from http://www.gnupg.org (optional)

• ssh2 library from http://www.libssh2.org (optional)
