AI Summary: The task involves creating a comprehensive backup system for a MediaWiki instance, ensuring complete rollback capabilities. This includes backing up the database (XML content, user data), file system (configurations, skins, images, extensions), and handling potential compatibility issues with extensions and generated content (e.g., Mermaid diagrams). The backup strategy should prioritize digital preservation and version control using Git, with a monthly XML backup and an annual full reinstall from XML. A separate public-facing Git repository will store only the latest version of the Wiki.
