It will depend on your power needs. What are your emergency loads? Fridge(s), freezer(s), lights, well pump?
Buy two small gas generators with Honda engines. 3000-5000W. The quieter the better. Electric start is a bonus.
I'd also plan for a backup battery always charged so that you can start one of your generators. Look for generators with the largest tank that will still allow you to move it around. Buy a small gas tank (250L+) with a hand pump and a couple of jerry cans.
Generators should be installed in a well-ventilated area, or outside, well away from your gas storage.
If you live in the country, you probably have a tractor so a small PTO generator could be your backup generator.
For cooking, you should buy a wood cookstove and build a shed for wood storage.
In an emergency situation, you will need electricity only for things like refrigeration, well pump and maybe a washing machine.
Lights, cooking can be done without electricity.
So plan accordingly.
