You are the one sticking your head in the sand. For critical company and personal data an external backup is not yours and not fully secure. It sits on someone else’s drives in a data centre. No one who has personal data for other people could tolerate such a loss of control over their files. Maybe if it’s encrypted before uploading but how many cloud providers provide for that- even, unfortunately, Apple doesn’t.
One has to read the post I was quoting to understand the head in the sand comment I made to that person. It was directed at someone that outright rejected cloud usage. Cloud has a purpose, and thus my comment.
Regarding you saying that to me, simply is because you don't understand my usage of the cloud, or to what lengths I go to ensure recoverability in my backup plan. I won't go into details here, as that would be far of the topic, but I can assure you that my recovery path is very redundant. Far beyond 11 9's, and consists of multiple forms of media, local, near local, and cloud, comprised of multiple physical and logical protections (ie; encryption everywhere, and yes I control the key).
