Backup of Nova Servers

The backup of a single Nova server takes the following steps:

• Export the Nova server metadata configuration for future restore.

• For each volume attached to the Nova server, the plugin issues a snapshot of the volume.

• Backup all volumes attached to the Nova server by ingestion on the proxy server.

• Cleanup the snapshot and volume created from snapshot after it is stored in the Bacula Enterprise Storage.

This is an example of the Job and Fileset resources to back up an instance named cirros-instance1, using the OpenStack RC file /opt/bacula/etc/openstack.conf located in the proxy server:

Job {
  Name = "openstack-cirros-instance1-job"
  Description = "Backup cirros-instance1"
  Type = "Backup"
  Accurate = yes
  Client = "bacula-proxy-vm-rhel9-fd"
  Fileset = "openstack-cirros-instance1-fileset"
  JobDefs = "BackupsToDisk"
  Messages = "Default"
  Pool = "DiskBackup365d"
  Schedule = "Manual"
  Storage = "DiskAutochanger"
}

Fileset {
  Name = "openstack-cirros-instance1-fileset"
  Include {
   Options {
    IgnoreCase = yes
    OneFs = no
    Signature = Md5
   }
   # Using authentication from /opt/bacula/etc/openstack.conf
   Plugin = "openstack: proxy_server=7172b28d-4d39-4e5a-9ece-d2c76768fd2b server=cirros-instance1 verbose=1"
  }
}

And a successful joblog of the Nova servers backup job run, using verbose=1 in the Plugin line in the Fileset:

Backup of Glance Images

This is an example of the Job and Fileset resources to backup all the Glance images only, using the OpenStack RC /opt/bacula/etc/openstack.conf file located in the proxy server:

Job {
    Name = "openstack-images-job"
    Description = "Backup OpenStack images"
    Type = "Backup"
    Accurate = yes
    Client = "bacula-proxy-vm-rhel9-fd"
    Fileset = "openstack-images-fileset"
    JobDefs = "BackupsToDisk"
    Messages = "Default"
    Pool = "DiskBackup365d"
    Schedule = "Manual"
    Storage = "DiskAutochanger"
}

Fileset {
    Name = "openstack-images-fileset"
    Include {
      Options {
        Signature = Md5
      }
      # Using authentication from /opt/bacula/etc/openstack.conf
      Plugin = "openstack: proxy_server=7172b28d-4d39-4e5a-9ece-d2c76768fd2b glance_image_backup=1 nova_server_backup=0 verbose=1"
    }
}

Note

The above backup will not include Nova servers, but Glance images only, by using nova_server_backup=0.

And a successful joblog of the Glance images backup job run, using verbose=1 in the Plugin line in the Fileset:
