My first concern is power failures that are extensive. Solution is a whole house generator (yes that is expensive, but I have multiple tanks, a pond, and four refrigerators). Second line of defense (with no generator) are battery operated air pumps. My second concern would be pump failure so I have an spare that would work on any aquarium (all sumps in the basement). 200 gallons of RO/DI water is last emergency provision.
Logically speaking, this is by far the most reasonable necessities, when you define the term, “Disaster Recovery” Geographics play a huge roll as well. Example for my location a tsunami is top of list. living 200 yard from the shoreline and an elevation of less than ten feet above sea level all the redundant back up parts in the world service no purpose in such aquaria disaster recovery plan. I do keep, a 6500W Yamaha and the necessary backup parts to repair, replace and sustain life under normal conditions or power outages . More or less a reef tool box.
