-We haven't documented this properly yet, but the general advice is to:
-
-- back up Postgres by making a database dump. See [Backing up PostgreSQL](maintenance-postgres.md#backing-up-postgresql)
-
-- back up all `/matrix` files, except for `/matrix/postgres/data` (you already have a dump) and `/matrix/postgres/data-auto-upgrade-backup` (this directory may exist and contain your old data if you've [performed a major Postgres upgrade](maintenance-postgres.md#upgrading-postgresql)).

-- Restoring the `/matrix` directory and files on the new server manually

 ### What is this `/matrix/postgres/data-auto-upgrade-backup` directory that is taking up so much space?
 
 When you [perform a major Postgres upgrade](maintenance-postgres.md#upgrading-postgresql), we save the the old data files in `/matrix/postgres/data-auto-upgrade-backup`, just so you could easily restore them should something have gone wrong.
 
 After verifying that everything still works after the Postgres upgrade, you can safely delete `/matrix/postgres/data-auto-upgrade-backup`
 
-### How do I debug or force SSL certificate renewal?
-
-SSL certificates are managed automatically by the [Traefik](https://doc.traefik.io/traefik/) reverse-proxy server.
-
-If you're having trouble with SSL certificate renewal, check the Traefik logs (`journalctl -fu matrix-traefik`).
-
-If you're [using your own webserver](configuring-playbook-own-webserver.md) instead of the integrated one (Traefik), you should investigate in another way.
