	==Structure==

	A Bacula installation contains three kinds of ] to execute backup and restore functionality:
	;Director Daemon: manages other daemons, queries and updates catalog, interfaces with operator front-ends, automates backup schedules
	;Storage Daemon: makes system calls to drive backup media, responds to read/write requests from Director, and receives backup/restore data from file daemon
	;File Daemon: negotiates client-side communication, encryption and compression, opens file handles to access a client's data
	;Bacula Console: the control interface from which the user can enter commands to operate Bacula tasks. the console is a ].
	;Bat (Bacula Administrative Tool) Console: a GUI interface from which the user can enter commands to operate Bacula tasks.
	;Tray Monitor: is a ] that can be installed on any desktop to monitor the Bacula operations.
	;Bweb: a web interface that allows systems management views of all the Bacula backups. It also permits most all operations that can be done with the console.

			==Considerations==
	These daemons can run on independent hosts but typical installations consist of three kinds of Bacula hosts:
	;Client machines: the machines that contain the files to be backed up
	;Storage machines: machines that contain the media used to store the backups
	;Backup Servers: that orchestrate the backup processes

			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 name=":0">{{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>
	The Director manages everything so is called a "backup server"; the client and storage daemons run as its subordinates and have no direct control of the back up process. While this structure suggests that the three daemons run on three different machines, an equally valid setup is to run all three daemons on the machine that controls the backup process and backup additional machines that have just a file daemon installed. It is also possible to mount remote files and storage resources into the Director's filesystem over ] or ], however, the Bacula developers discourage this in favor of having a File daemon installed on each machine to be backed up. In practice, however, the Director and Storage Daemon are often run on one machine (often referred to as the Bacula Server). The File Daemon is then run on each machine to be backed up (including the Bacula server—because its catalog is dumped as ]).

	Backup data can be stored on various media, including tape, and disk.

	==Limitations==

	Bacula stores backup data in an open and documented yet unique volume format; there are Bacula standalone tools to read/write the backup data (bls, bcopy, bscan, bextract), these tools are not compatible with other Unix backup utilities such as ] or ].

	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.<ref>{{cite web\|url=http://www.bacula.org/3.0.x-manuals/en/concepts/concepts/New_Features_in_3_0_0.html#428 \|title=New Features in 3.0.0 \|publisher=Bacula.org \|date= \|accessdate=2012-06-09}}</ref>

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 Linux, UNIX, Windows, and 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 MySQL, PostgreSQL, or 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 AGPL version 3 license with exceptions to permit linking with OpenSSL and distributing Windows binaries.

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 sells various levels of annual support contracts for "Bacula Enterprise Edition", which contains various non-GPL components developed in-house.

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.

Features

Bacula's features include:

Network options

TCP/IP – client–server communication uses standard ports and services instead of RPC for NFS, SMB, etc.; this eases firewall administration and network security
CRAM-MD5 – configurable client–server authentication
GZIP/LZO – 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 – enterprise version plugin
cloud backup with some S3 file storage services

Client OS

The client software, executed by a "file daemon" running on a Bacula client, supports multiple operating systems.

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.
