Backup
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 backup 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
The backup of the Glance images will generate a temporary file named img-<number>.tmpimg in the /opt/bacula/working
directory of the Bacula proxy server:
# ls -l /opt/bacula/working/*.tmpimg
-rw-r-----. 1 root bacula 0 May 13 11:18 /opt/bacula/working/img-9359619567641477501.tmpimg
Upon completion, this file is stored in the Bacula Storage used by the backup job and subsequently deleted from the /opt/bacula/working
directory.
Note
It is recommended to have enough space in the /opt/bacula/working directory of the Bacula proxy server to
store the img-<number>.tmpimg temporary file for Glance images backups. The space should be at least equivalent to the size
of the largest Glance image in the OpenStack server. When running concurrent backups of Glance images,
additional space will be necessary to hold the img-<number>.tmpimg temporary files generated by the concurrent jobs.
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"

Storage = "DiskAutochanger"
}
Fileset {

}
}
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:
