Introduccion

Bacula es un sistema de copias de seguridad que funciona como cliente y servidor. Este sistema de copias de seguridad va a ser instalado en una de las maquinas virtuales de nuestro escenario openstack que hemos creado en posts anteriores, mas concretamente como bacula necesita de una base de datos mariadb, se usara nuestra maquina Sancho (servidor de base de datos del escenario openstack) como servidor de copias de seguridad y las demas maquinas haran de clientes.

Instalación en el servidor

sudo apt install bacula bacula-client bacula-common-mysql bacula-director-mysql bacula-server

Postfix-configuration → En este caso No configuration.
Password para bacula → backup.

Configuracion del director (/etc/bacula/bacula-dir.conf):

Director {                            # define myself
  Name = sancho-dir
  DIRport = 9101                # where we listen for UA connections
  QueryFile = "/etc/bacula/scripts/query.sql"
  WorkingDirectory = "/var/lib/bacula"
  PidDirectory = "/run/bacula"
  Maximum Concurrent Jobs = 20
  Password = "backup"         # Console password
  Messages = Daemon
  DirAddress = 10.0.1.8		#tambien podemos poner localhost
}
  • Name → nombre del director.
  • DIRport → puerto por el que el director va a escuchar las peticiones de bacula.
  • QueryFile → ruta del directorio y el fichero usador por el director.
  • WorkingDirectory → ruta donde se colocan los ficheros estaticos.
  • PidDirectory → el directorio en el que el Director colocará los ficheros de id de los procesos.
  • Maximum concurrent jobs → numero máximo de trabajos que el director puede correr.
  • Password → contraseña de la consola backula.
  • Messages → especifica donde tiene que entregar el DIrector los mensajes que no están asociados con un trabajo especifico.
  • DirAddress → especifica los puertos y las direcciones IP donde escuchará el Director por conexiones Bacula mediante consola.
