I am looking for a UPS for a single Fedora server for a non-profit
org. Only one machine (HP DL360 G4) will be connected to the UPS. We
need about 2 hrs of run-time, with automatic shutdown capability, and
restart when the power comes back.

Any good APC UPS that has rpm for Fedora?
For that long of a time you may want to look into some sort of backup
generator. You can get ones that run off natural gas for a few thousand
dollars. (If you expect earthquakes, than getting one that runs on gas or
diesel would make more sense. Those are more of a pain to maintain, since
you have to worry about stabilizing the fuel.) That device could also supply
power for other things in the office. You would still want a UPS to smooth out
the cutover and help clean up the power during normal operation.
I would have thought that, in case of an earth quake, you'd want the power off so as to not cause more fires. If the power's down, probably the communications are down too, unless you're an emergency service.

But then we haven't had a significant quake here since September 1968, and when we did the epicentre was far from built-up areas. What would I know?

I have a genset for the house, but I live in Southern California with
our propensity for earthquakes. It's not only good for those, but for
brush fires as well.

While I wasn't affected during the fires (other than dealing with a lot
of smoke, soot and ash), a friend (whom I convinced to get a small
genset) was. His was the only house with power since the high-tension
lines were fried by the fire and it ended up being used as a command,
coordination, staging and rest area for police and fire people. He's a
HAM, so his radios could also be used. His refrigerators and freezers
kept going, so he was also able to keep donated food cold and cook for
the emergency workers. I think he said he and his wife fed about 300 of
them over two days. Turned out rather well for all.

Oh, his genset runs off LP gas in an underground tank.

And he was on hand to adjudge it safe. I was thinking more of when buildings fall over (as happened in the quake I mentioned, but that was Tammin, quite a small place). At least one building in Perth did crack and the crack was visible from the street.

If there's nobody on had to decide it's safe, I would rather no volts. B'sides, if there's serious building damage, who cares about the average server?
