Backup and restore OpenStack databases¶
Mirantis OpenStack for Kubernetes (MOSK) relies on the MariaDB Galera cluster to provide its OpenStack components with reliable storage of persistent data. Mirantis recommends backing up your OpenStack databases daily to ensure the safety of your cloud data. Also, you should always create an instant backup before updating your cloud or performing any kind of potentially disruptive experiment.
MOSK has a built-in automated backup routine that can be triggered manually or by schedule. Periodic backups are disabled by default.
Also, MOSK provides means for the OpenStack database restoration from a previously made backup that can be used to recover the cloud after a failure.
