'''Bacula''' 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.

Bacula supports [[Software:Linux|Linux]], UNIX, [[Software:Microsoft Windows|Windows]], and [[Software:MacOS|macOS]] backup clients, and a range of professional backup devices including tape libraries.  Administrators and operators can configure the system via a command line, GUI or web interface; its back-end is a catalog of information stored by [[Software:MySQL|MySQL]], [[Software:PostgreSQL|PostgreSQL]], or [[Software:SQLite|SQLite]].

==Overview==

Bacula 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.

Bacula is open-source and released under the [[Software:GNU Affero General Public License|AGPL version 3]] license with exceptions to permit linking with OpenSSL and distributing Windows binaries.<ref>{{cite web |url=http://www.bacula.org/7.0.x-manuals/en/main/Bacula_Copyright_Trademark_.html |title=Bacula Copyright, Trademark, and Licenses |publisher=Bacula.org }}</ref>

Bacula is available under a "dual license" (see [[Multi-licensing]]) AGPLv3 or Proprietary license. Several entities offer commercial support for the AGPL "Bacula community version" while Bacula Systems<ref>{{cite web |url=http://www.baculasystems.com |title=Bacula Systems S.A.}}</ref> sells various levels of annual support contracts for "Bacula Enterprise Edition", which contains various non-GPL components developed in-house. In 2015, Bacula Systems was named "Top 20 Most Promising Data Center Solution Providers" by CIO Review.<ref>{{cite web | url=http://datacenter.cioreview.com/vendors/2015/20special1 | title=June 2015 Data Center special edition | publisher=CIO Review | accessdate=10 June 2015 | author=10 June 2015 | archive-date=10 June 2015 | archive-url=https://web.archive.org/web/20150610215641/http://datacenter.cioreview.com/vendors/2015/20special1 | url-status=dead }}</ref>

In common with other dual-license software, components developed for the Bacula Enterprise Edition are released into Bacula Community edition after some period of exclusivity to the proprietary version.

Since April 2002, Bacula has over 2 million downloads, which makes it the most downloaded open-source backup program.<ref>{{Cite web|url=http://sourceforge.net/projects/bacula/|title=Bacula}}</ref>

==Features==

Bacula's features include:

===Network options===

*[[Transmission Control Protocol|TCP]]/[[Internet Protocol|IP]] – client–server communication uses standard ports and services instead of [[Remote procedure call|RPC]] for NFS, [[Server Message Block|SMB]], etc.; this eases firewall administration and network security
*[[CRAM-MD5]] – configurable client–server authentication
*[[Software:Gzip|GZIP]]/LZO – client-side [[Data compression|compression]] to reduce network bandwidth consumption; this runs separate from hardware compression done by the backup device
*[[Transport Layer Security|TLS]] – network communication encryption<ref>{{Cite web|url=https://www.bacula.org/9.4.x-manuals/en/main/Bacula_TLS_Communications_E.html|title = Bacula TLS – Communications Encryption}}</ref>
*[[MD5]]/[[SHA-1|SHA]] – verify file integrity
*[[Cyclic redundancy check|CRC]] – verify data block integrity
*[[Public key infrastructure|PKI]] – backup data encryption
*[[NDMP]] – enterprise version plugin<ref>[http://www.baculasystems.com/products/bacula-enterprise-plugins Bacula Enterprise Plugins]</ref>
*cloud backup with some [[Amazon S3|S3]] file storage services

===Client OS===

The client software, executed by a "file daemon" running on a Bacula client, supports multiple operating systems.<ref>{{cite web|url=http://www.bacula.org/7.0.x-manuals/en/main/Supported_Operating_Systems.html |title=Supported Operating Systems |publisher=Bacula.org }}</ref>

==Considerations==

By default, Bacula's differential and incremental backups are based on system time stamps. Consequently, if you move files into an existing directory or move a whole directory into the backup FileSet after a full backup, those files may not be backed up by an incremental save because they may have old dates. You must explicitly update the date/time stamp on all moved files. Bacula versions starting with 3.0 or later support Accurate backup, which is an option that addresses this issue without requiring modification of the files timestamps. This feature should always be used if an accurate state of the filesystem is important. Which criteria should be applied is configurable, i.e. inode comparisons, modification times or md5/sha1 signatures.<ref>{{cite web|url=http://www.bacula.org/7.0.x-manuals/en/main/Released_Version_3_0_3_3_0_.html#SECTION00520000000000000000 |title=New Features in 3.0.0 |publisher=Bacula.org}}</ref>
