How to upgrade

Upgrade backup-integrator and bacula-fd

The backup-integrator and bacula-fd are both stateless charms, meaning they don’t store persistent data that could be lost during an upgrade. This makes the upgrade process for both the charms straightforward.

Upgrade the charms with the refresh command:

juju refresh backup-integrator
juju refresh bacula-fd

Upgrade bacula-server

The bacula-server is a stateful charm as it maintains persistent data in its PostgreSQL database. Before upgrading the bacula-server charm, you must back up the PostgreSQL database.

Follow the PostgreSQL documentation for instructions on how to create a backup of the postgresql charm.

After confirming the PostgreSQL backup is complete, upgrade the bacula-server charm:

juju refresh bacula-server

Verify the upgrade

After upgrading, verify that the charms are functioning correctly with the juju status command. The upgraded charms must be in active and idle state.
