Back up MariaDB on an OpenStack-based management cluster

Container Cloud uses a MariaDB database to store data generated by the Container Cloud components. Mirantis recommends backing up your databases to ensure the integrity of your data. Also, you should create an instant backup before upgrading your database to restore it if required.

After the management cluster deployment, the cluster configuration includes the MariaDB backup functionality for the OpenStack provider.

The Kubernetes cron job responsible for the MariaDB backup is enabled by default to create daily backups. You can modify the default configuration before or after the management cluster deployment.


For other supported Container Cloud providers, the MariaDB backup functionality is disabled and will be enabled in one of the following releases.
