Two kVA UPS backed by a 24 volt, 600 amp-hour battery bank. That's good for almost 24 hours at my current loading. Because I live in a remote mountain cabin, I depend on electricity for my well water also. Therefore before a day passes, the 10kVA generator comes out to power up the well pump, the water heater, the heat pump and the electric stove. Nine days is the longest that I've been without power. I have a wood stove insert for my fireplace for heat, the fan of which is powered from the UPS. There is an 80 amp charger for the batteries that is powered up whenever utility or generator power is available. For backup to the backup, I can use the 4kVA generator in my motorhome to run everything except the heat pump.
