Outline Backup

Outline Backup is a backup management system for the Outline Knowledge Base that provides a visual interface to configure Outline nodes, manage WebDAV storage, and supports manual and scheduled task backups. The system can upload backup files to the WebDAV directory and supports two modes of "secure storage/encrypted storage", where encrypted storage will encrypt the generated compressed package with AES-256. The project has a built-in account system and optional OIDC single sign-on configuration, which is suitable for self-managed deployment (Docker/containerization) and used for long-term stable backup and recovery scenarios.
