Bacula is a very powerful enterprise level backup solution which can backup localhost, and even remote host via network. It has these components<\/p>\n
The installation process is pretty straight forward in Redhat Linux or CentOS. The OS that I used in my lab is CentOS 7. I am sure it will be similar on others\u00a0Redhat and CentOS systems too<\/p>\n
Let us begin by installing all required packages in an updated CentOS system<\/p>\n
#] yum install -y bacula-director bacula-storage bacula-console bacula-client mariadb-server<\/em><\/strong><\/p>\n Let us start the DB server Let us granted user bacula Privileges on database by running a scrip that got installed when other packages were installed Let us create bacula databases using the pre-istalled script Let us create the tables used by bacula\u00a0using the pre-installed script Secure the Database server by assigning a Root Password and leaving the remaining option with default value<\/p>\n #]<\/strong>mysql_secure_installation<\/p>\n Let us assign a password for the root user in MariaDB server. Login to the server as root and run the following command: Let us flush the user privileges in the DB server Exit from MySQL console<\/p>\n Let us\u00a0ensure the database server starts during the startup of the host<\/p>\n #] systemctl enable mariadb<\/em><\/strong><\/p>\n By default bacula is set to use the PostgreSQL<\/em>. The the following command is used to enable MySQL as the default. When you get the menu, select 1<\/strong><\/em><\/p>\n #] alternatives –config libbaccats.so<\/em><\/strong><\/p>\n Let us make a two folders in the server. This is where we can plan to backup and restore files and folders. Ensure this is in a partition that has huge space to store all backups The server installation and setup is kind of done. Now we need to configure the server.<\/p>\n We will start with the Director. Ensure the last line is added to the below block<\/p>\n Director { # define myself<\/em> Now we need to create a “Job” to backup the localhost. Find the Name parameter in defined Job that reads “BackupClient1” and replace it with “BackupLocalFiles”<\/p>\n == === =<\/p>\n Job {<\/em> == === =<\/p>\n Now you may want to change the default location of where files should be restored from “\/tmp\/bacula-restores” to “\/bacula\/restore<\/strong>” and change the Job name “RestoreFiles” to “RestoreLocalFiles” so that it make meaning.<\/p>\n ====== =====<\/p>\n Job { ====== =====<\/p>\n You may want to edit the FileSet, named “Full Set” that defines the files that needs to be backed from the localhost. In this example we will backup the folder \/home\/user1. Ensure gzip compression is used, and only \/home folder is backed.<\/p>\n ======================= ====== In the Storage parameter with name as “File” ensure the address parameter has the value as the actual hostname resolvable to an IP by the localhost. Ensure we do not use the value “localhost”. My host’s FQN is myhost.mydomain.local<\/p>\n ===== ==== === ===== ==== ===<\/p>\n In the catelog section named “MyCatalog” ensure the correct password for for the dbname, dbuser and password is used<\/p>\n ====*====== ===<\/p>\n Catalog {<\/em> ====*====== ===<\/p>\n In the Pool definition named “File”, it will be good to use a “Label Format” parameter to identify the host that is stored. For example “myLocalhost-”<\/p>\n ===== === == ==== == Now we are in a position to check if there are any syntax error in the configuration file by running the following command: Check for any error message<\/p>\n **************** Storage Daemon configuration ************<\/p>\n The configuration file for the storage daemon is bacula-sd.conf.\u00a0<\/em>Since the storage server is also the same server, add the hostname of the same server in Storage parameter named “BackupServer-sd”. This is done by adding a line “SDAddress = myhost.mydomain.local”<\/p>\n ==== === === === In the Device parameter named “FileStorage” ensure the place where backup is stored is changed to “Archive Device = \/bacula\/backup”<\/p>\n === === === === Now verify the storage configuration: Now it is time to change bacula-dir passwords used in files.<\/p>\n ]#<\/strong> sudo sed -i “s\/@@DIR_PASSWORD@@\/my_bacula_pw\/” \/etc\/bacula\/bacula-dir.conf<\/strong><\/em> ======************=======<\/p>\n Now we are ready to start Bacula<\/p>\n ]# sudo systemctl start bacula-dir<\/em><\/strong> ]# sudo systemctl enable bacula-dir<\/em><\/strong> <\/p>\n ******* ******* ********<\/p>\n Installation is complete now you can start managing the backup application by using the <\/p>\n Process to test backup and restore can be found “here<\/a>“<\/p>\n","protected":false},"excerpt":{"rendered":"
