Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set will cover all product layers, including MOSK management (formerly MCC). This means everything you need will be in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

OpenStack database

MOSK relies on the MariaDB Galera cluster to provide its OpenStack components with a reliable storage of persistent data.

For successful long-term operations of a MOSK cloud, it is crucial to ensure the healthy state of the OpenStack database as well as the safety of the data stored in it. To help you with that, MOSK provides built-in automated procedures for OpenStack database maintenance, backup, and restoration. The hereby chapter describes the internal mechanisms and configuration details for the provided tools.

• Overview of the OpenStack database backup and restoration
• Workflows of the OpenStack database backup and restoration
• OpenStack database auto-cleanup
• Periodic OpenStack database backups
• Remote storage for OpenStack database backups
• Synchronization of local MariaDB backups with a remote S3 storage
