Isn't that self-evident? Do you have two microwaves from different batches, regularly tested, solely for the eventuality that one breaks? Systems work fine until some (unlikely) risk manifests...
Idk if this sounds like I'm against backups, I'm not, I'm just surprised by the question
It works fine as long as it doesn't break, and it's cheaper to buy than an equivalently sized system that does have back ups.
