LOL... Dokku on DO is pretty simple... as to backups, it's a checkbox option, as to redundancy, for non-revenue generating projects, it's generally acceptable to have some down time. As to back up again, beyond some potential data loss, it's pretty easy to get CI/CD up and pushing to Dokku.

In any case, it doesn't need to be as completely flushed out as a company with millions in investment capital could do.
