Backups & Persistence

What to back up

• SQLite DB: DB_PATH (default /data/middleware.db) — contains middlewares, services, assignments, mTLS state.
• Traefik static config: /etc/traefik/traefik*.yml — plugins, entrypoints, logging, providers.
• Templates: /app/config/templates.yaml, /app/config/templates_services.yaml.

Backup cadence

• DB: before major changes; daily for active environments.
• Static config: any time plugins/entrypoints/logging change; keep under version control.

Restore guidance

• Stop Middleware Manager before restoring the DB to avoid concurrent writes.
• After restoring static config, restart Traefik to apply plugins/entrypoints/logging.
• Invalidate cache (/api/traefik-config/invalidate) so regenerated rules match DB state.
