SAC:Bacula

As of 2017 Bacula server runs on the SAC:Backups host.

As of 2023 Bacula version 9.4 is running.

Overview of components can be found here: https://www.bacula.org/9.4.x-manuals/en/main/What_is_Bacula.html#SECTION00220000000000000000

The backup.osgeo.org machine is acting as the `Bacula Director`

Configuration

As of November 2023 Bacula director configuration is under ansible. For full details, see https://git.osgeo.org/gitea/sac/ansible-deployment/src/branch/master/deployment/roles/bacula-director (private repo)

Specific configuration of the file/tape storage is in the Storage director /etc/bacula/bacula-sd.conf

• Bacula uses the hard drive as a series of Tape drives.
• Each Volume is a predetermined size (~500MB currently), when a volume fills bacula makes the next one.
• Volumes older than a certain date or when volume increments have reach a configured maximum can be recycled into the available disk pool.

Administration

To review the backups and perform a restore you can use the bconsole application:

 sudo bconsole

Once in console:

   list jobs #lists all jobs
   list job=BackupWiki  #list all jobs with specific name and shows the dates and job id of each
   list joblog jobid=21541 #list details of a job like how many bytes backed up, date and # of files backed up
   list files jobid=21541 #Lists the actual files backed up in this run
   list clients #list all job clients (each is dedicated to servicing a particular backup
   run job=BackupWeb18a #manually triggers a named job to run and will return the job id

Recovery

• If you use bconsole to recover data bacula does the work of finding the files you want and pulling them out of the various volumes.
• Directory for recovered files is set in the bacula-dir.conf under:

Job {
 Name = "RestoreFiles"
 Type = Restore
 Client = backup.osgeo.osuosl.org-fd
 FileSet = "Full Set"
 Storage = File
 Pool = Default
 Messages = Standard
 Where = /tmp/bacula-restores
}

• Directions for how to restore

sudo bconsole
*restore

Then follow the prompts, using the above linked guide to help find the files you want.
