Is there any sort of backup in case it gets destroyed or lost? Can you clone it?

The entire security model depends on the devices being uncloneable.

But my security model does not allow putting myself in a position where I am stranded without my second factor (or doing huge amounts of work re-registering everything).

That's why you set up backup factors.

It is for the same reason that services like Google Mail won't let you set up a U2F token without a backup factor.

The only backup I know of is getting another key that you register in the same way as the first key.

Hopefully they don't both break at the same time.
