I have a decade old lenovo yoga that still lasts like 40 minutes unplugged. Idunno how much a UPS that can supply a desktop for that long would cost, nor if that's an embarrassingly short time, but it works well enough for me

UPS systems are generally configured for 90 minutes of operation, depending on the criticality of the system they're connected to. The best ones are programable and will actually send graceful shutdown signals (when configured to do so) to your server cluster to prevent data loss that occurs during system blackouts. You can emulate this behavior on your laptop with a script that checks battery% every 10-15 minutes, sending a shutdown signal if it falls below a treshhold you set.

honestly for a home server i'd be happy with like 10 minutes battery life, just need enough to let the computer survive tripping a breaker and resetting it.

an actual outage is basically an act of god and not worth worrying about for something you can just.. push the power button on

Size right for your setup and risk tolerance. Just know every outage can come with data loss. Most do not, but it is not a guarantee.
