Earlier quoted context omitted.
You’re right, but also I know I have enough backed up to survive a catastrophe. What I don’t want to do is to test my backup in a non catastrophe situation and invalidate all my TOTP, WhatsApp history, mail settings etc. just because I wanted to test disaster recovery. It feels like buying a fire safe (phone and app backups) without any kind of understanding if it works then burning your house down to see if it works…
Analogies only go so far. Going to the store, buying gasoline and rags and a lighter and then committing arson and burning my house down is maybe a little bit different from sitting down for a few hours with my laptop connected to my phone.
It's quite easy to restore an icloud backup to a different phone or even ipad for testing purposes, if one were reliant on icloud to hold their data.
