    Bareos is an open source, enterprise level computer backup system for heterogeneous networks. It is designed to automate backup tasks that had often required intervention from a systems administrator or computer operator.

    Bareos supports Linux, UNIX, Windows, and Mac OS X backup clients, and a range of professional backup devices including tape libraries. Administrators and operators can configure the system via a command line console, GUI or web interface; its back-end is a catalog of information stored by MySQL, PostgreSQL, or SQLite.


    Bareos is a set of computer programs for managing backup, recovery, and verification of computer data across a network—providing a backup solution for mixed operating system environments.

    In 2010 a former Bacula community developer (with several other Free Software users) started Bareos as a fork of Bacula. [1]

    Bareos is open source and released under the AGPL version 3.

    Bareos is one of the backup solutions used by Univention Corporate Server.,[2] it is included in several Linux distributions like Debian[3]

    The open source platform Open Hub counts more than 580.000 lines of code, more than 30 current contributors and affirms "High Activity".[4] According to Bareos own information, the number of daily unique visitors on the official download site exceeded 20.000 in April 2016.[5]

    In December 2015 the inter-ministerial working group on free software of the French government (Socle Interministériel de logiciel libre) included Bareos on their recommendation list among 130 other open source programs.[6]


    Bareos's features include:

    Network options[edit]

    • TCP/IP - client–server communication uses standard ports and services instead of RPC for NFS, CIFS, etc.; this eases firewall administration and network security
    • CRAM-MD5 - configurable client–server authentication
    • GZIP/LZO/LZ4 - client-side compression to reduce network bandwidth consumption; this runs separate from hardware compression done by the backup device
    • TLS - network communication encryption
    • MD5/SHA - verify file integrity
    • CRC - verify data block integrity
    • PKI - backup data encryption
    • NDMP - Direct storage backup
    • Bandwidth Limitation


    • VSS - calls Microsoft's snapshot service
    • Full and incremental backup of VMWare[7][8] virtual machines.

    Backup devices[edit]

    • pooling - allocates backup volumes according to job needs and retention configuration
    • spooling - writes backup data to spool until target backup medium is allocated so jobs can continue uninterrupted
    • media-spanning - such as spanning tapes
    • multi-streaming - write multiple, simultaneous data streams to the same medium
    • ANSI & EBCDIC - IBM compatibility
    • Barcodes - reading tape barcodes in libraries
    • autoloaders - virtually every tape autoloader available (called autochangers in Bareos)
    • most tape drives, including DDS, DLT, SDLT, LTO-1-6
    • hardware encryption since LTO version 4
    • locations - tapes can be "out" of a library, allowing off-site storage
    • Cloud storage: Bareos has native Ceph (software) and Gluster[9][10] connectors, to backup from an to cloud storages.

    Client OS[edit]

    The client software, executed by a "file daemon" running on a Bareos client, supports multiple operating systems. Users and administrators can also use a web UI to manage the backup system.


    The project publishes installation packages for each major release for the common Linux distributions, Windows and Mac.
