Bareos is a set of computer programs that permits you (or the system administrator) to manage backup, recovery, and verification of computer data across a network of computers of different kinds. In technical terms, it is a network Client/Server based backup program. Bareos is relatively easy to use and efficient, while offering many advanced storage management features that make it easy to find and recover lost or damaged files. Due to its modular design, Bareos is scalable from small single computer systems to systems consisting of hundreds of computers located over a large network.
Bareos Director service consists of the program that supervises all the backup, restore, verify and archive operations. The system administrator uses the Bareos Director to schedule backups and to recover files. The Director runs as a daemon or a service (i.e. in the background).
Bareos Console services is the program that allows the administrator or user to communicate with the Bareos Director.
Bareos File services (or Client program) is the software program that is installed on the machine to be backed up. It is specific to the operating system on which it runs and is responsible for providing the file attributes and data when requested by the Director. The File services are also responsible for the file system dependent part of restoring the file attributes and data during a recovery operation. This program runs as a daemon on the machine to be backed up, and in some of the documentation, the File daemon is referred to as the Client (for example in Bareos’s configuration file).
Bareos Storage services consist of the software programs that perform the storage and recovery of the file attributes and data to the physical backup media or volumes. In other words, the Storage daemon is responsible for reading and writing your tapes (or other storage media, e.g. files). The Storage services runs as a daemon on the machine that has the backup device.
Catalog services are comprised of the software programs responsible for maintaining the file indexes and volume databases for all files backed up. The Catalog services permit the System Administrator or user to quickly locate and restore any desired file. The Catalog services sets Bareos apart from simple backup programs like tar and bru, because the catalog maintains a record of all Volumes used, all Jobs run, and all Files saved, permitting efficient restoration and Volume management. Bareos supports multiple databases (e.g. MySQL, PostgreSQL, ...).
Each daemon has its own configuration file which must be tailored for each particular installation. Please see the HTML/PDF documentation for the details.
