It is more a function of how long of a power outage do you need to handle? If you look at the power supply that comes with the Weaver, you can see the maximum voltage and current the supply takes at the mains input. With this you can compute VA (volt-amperes) which is the standard measurement of a UPS capacity.
In the example above, the maximum VA it consumes would probably be at the minimum input voltage and maximum current, so 100 x 2.2 = 220 VA.
I used an older APC Smart UPS 1000 on my Draken I to help keep the printer, computer and DLP projector running during brownouts or small drops. I wouldn't expect it to last more than 30 minutes during a full power outage.

The power supply for Weaver is 24V 3A. Like Ron said, battery backup won't last long. I have a power generator in the garage for winter power outage~
