Before configuring bacula you need to know the following things about bacula
How Bacula works
Bacula relies on three important daemons that run in the background on the Servers and Clients. The Daemons namely are,
The Bacula-Director is considered the heart of the Bacula Backup Solution. The following sections explain in details all these daemons.
The Bacula-Director is considered as the heart of the Bacula Backup system. This Daemon controls the whole backup system and the various other daemons (mainly Bacula-FD & Bacula-SD) to facilitate successful backups. All the default configurations for the backups are configured for this including the Schedules and the media library (pools).
The Server running the Bacula-Director daemon is considered to be the Bacula Backup Server
This daemon should be running in the background for the Bacula backup solution to work .
The Start-up script for the Bacula-Director is,
Bacula-SD is the Bacula Storage Daemon. As the name implies, it takes care of all the various Storage devices or otherwise called as Archive devices. This supports Archive devices including but not limited to Disks, Tapes and CD/DVDs.
There can be more than one Storage Daemon supporting more than one device on any number of servers in the network including the Bacula backup servers. The Bacula-Director can handle control all these Storage daemons without any problem. It also supports multiple concurrent writes to each device, although this may not be a preferred solution in most cases.
This daemon is required to be running at least at the time of backup. Hence, this service is also configured to start and run in the background at the system start-up.
The start-up script is
Bacula-FD is the File Daemon or in other words the client daemon, which should be run on every server that needs to be backed up. This includes the Bacula Backup Server as well in case the server has files to be backed up. Mostly, this is run on the Backup server because it is important to take a backup of the Bacula Backup Catalog required to restore data in case of a disaster.
There is a separate Windows client available as well to backup Windows Servers. The config for windows clients is not discussed as it is beyond the scope of this document.
The start-up script is
The bconsole is the Bacula Console that can be used to make changes and update once the Backup solution is implemented. This is not exactly a daemon but is a console utility that starts and runs whenever a user logs onto the console. This is not required to start and run in the background hence no start-up scripts.
Bsmtp is the smtp utility used by Bacula to end email messages to contacts on various messages including all job status. Bacula runs this utility when a message or alert is sent by Bacula-Director daemon.
The BootStrapRecord is the most critical record that has to be backed up on a different server or a CD or a external media other than the tape media itself. This is required to rebuilt in the event of a disaster to the backup server itself
