It would take a pretty large rack of batteries, to

powerwall (~$10K magnitude) is one pre-packaged way
to do it. The longest conventional power failure
I've had here, was 24 hours, for a relatively minor
issue. The longest unconventional failure might have
been three days (nuclear reactors all scrammed). During
the ice storm more than ten years ago, some rural sites
were without power for two weeks. Maybe a $100K worth
of Powerwalls could handle that. At some point, it
becomes absurd to prop up the PC :-)

There comes a point where a generator becomes economic. OK, you've got
to have fuel for it, but the energy density ... Though you've also
(assuming you truly want the U of UPS) got to switch over while you've
still got enough power to start it, and a way to instigate that.
