The only things I can think of do involve a ups. There are battery banks that support pass through charging but I’m not sure if you’re supposed to use that constantly. A low capacity power strip style ups seems like the next best. Or don’t use a pi at all - if you have an old laptop that you don’t use, that could be the server and it has its own built in ups.

Sorry I don’t know that I’m being helpful here. I had the same issue and just ended up with an ups - but I also ended up plugging my networking rack into it (router, cable modem, switch, nas) as well. We’ve only had one real outage since I set this up, but it kept my network alive for 90 minutes or so and then the power came back up.
