"Our nines go to eleven" Well written, but there are other significant risks like losing access credentials (e.g. a password stored only on one device that is destroyed in the same accident in which its only user, who remembered the password by heart, dies) or being hacked by someone who gains access to cloud storage and intentionally erases or corrupts data.
