This is where LLMs have been the most helpful for me. There are many ways to make your homeserver more robust, automatically run backups and updates etc., but setting them up properly takes time. I now use "infrastructure and code", i.e. I have a git repo with Ansible scripts that can reproduce my entire server configuration. Using coding agents I can easily add and configure services, and by having an agent ssh into my server I can summarize logs or debug if there is an issue. The setup is now way more stable and better protected than anything I ever made manually.
