Bacula - The Network Backup Solution
SYNOPSISbacula-dir - Directorbacula-fd - File daemon or Clientbacula-sd - Storage daemonbconsole - Console to control Baculawx-console - GUI Console
Bacula is a set of computer programs that permits you (or thesystem administrator) to manage backup, recovery, andverification of computer data across a network of computers ofdifferent kinds. In technical terms, it is a networkClient/Server based backup program. Bacula is relatively easy touse and efficient, while offering many advanced storagemanagement features that make it easy to find and recover lost ordamaged files. Due to its modular design, Bacula is scalablefrom small single computer systems to systems consisting ofhundreds of computers located over a large network.
Bacula Director service consists of the program that supervisesall the backup, restore, verify and archive operations. Thesystem administrator uses the Bacula Director to schedule backupsand to recover files. For more details see the Director ServicesDaemon Design Document in the Bacula Developer's Guild. TheDirector runs as a daemon or a service (i.e. in the background).
Bacula Console services is the program that allows theadministrator or user to communicate with the Bacula Director(see above). Currently, the Bacula Console is available in threeversions. The first and simplest is to run the Console programin a shell window (i.e. TTY interface). Most systemadministrators will find this completely adequate. The secondversion is a GNOME GUI interface that for the moment (07 October2005) is far from complete, but quite functional as it has mostthe capabilities of the shell Console. The third version is awxWidgets GUI with an interactive file restore. It also has mostof the capabilities of the shell console, allows commandcompletion with tabulation, and gives you instant help about thecommand you are typing.
Bacula File services (or Client program) is the software programthat is installed on the machine to be backed up. It is specificto the operating system on which it runs and is responsible forproviding the file attributes and data when requested by theDirector. The File services are also responsible for the filesystem dependent part of restoring the file attributes and dataduring a recovery operation. For more details see the FileServices Daemon Design Document in the Bacula Developer's Guide.This program runs as a daemon on the machine to be backed up, andin some of the documentation, the File daemon is referred to asthe Client (for example in Bacula's configuration file). Inaddition to Unix/Linux File daemons, there is a Windows Filedaemon (normally distributed in binary format). The Windows Filedaemon runs on all currently known Windows versions (98, Me,NT, 2K, 2003, XP).
Bacula Storage services consist of the software programs thatperform the storage and recovery of the file attributes and datato the physical backup media or volumes. In other words, theStorage daemon is responsible for reading and writing your tapes(or other storage media, e.g. files). For more details see theStorage Services Daemon Design Document in the Bacula Developer'sGuild. The Storage services runs as a daemon on the machine thathas the backup device (usually a tape drive).
Catalog services are comprised of the software programsresponsible for maintaining the file indexes and volume databasesfor all files backed up. The Catalog services permit the SystemAdministrator or user to quickly locate and restore any desiredfile. The Catalog services sets Bacula apart from simple backupprograms like tar and bru, because the catalog maintains a recordof all Volumes used, all Jobs run, and all Files saved,permitting efficicient restoration and Volume management. Baculacurrently supports three different databases, MySQL, PostgreSQL,and SQLite, one of which must be chosen when building Bacula.

for details of the command line options.
Each daemon has its own configuration file which must betailored for each particular installation. Please see the HTML/PDFdocumentation for the details.
