No shame in it, I myself have one, but you shouldn't be concerned with this scenario even if it happens.
Life is too short to waste on ruining your life over planning on how to ruin your life even further after a rare life ruining event has occurred. I doubt you'd be working, or having any real coherent thoughts, for many years in that scenario.
So you'd lose your friends and potentially your livelihood and any ability to financial support yourself, or any surviving friends or family, just because you don't want to use cloud backups or a professional backup service with the correct contingencies in-place ?
One could easily imagine a less dramatic scenario where your office is close to your work, you go home with your backups in your backpack; However a flood hits your town, you accidentally leave your your backpack behind at evacuation time. Your office and home are flooded and then your backups and actual data set is destroyed, no one dies but you've lost your company and not just phsycial assets. Seems a little unnecessary ?
I actually have lived in towns where floods, lighting storms and tornadoes have caused situations where this scenario could've easily played out.
I also feel the need to point out there's no need to suggest people need a psychiatrist when planning for a worst case scenario, some people are are just prepared for the worst, whether or not it's just how they're born or their paid /trained to do so.
What I'm against isn't the cloud existing, it's your 24x7 uptime guarantee during the equivalent of Hurricane Katrina at the cost of over engineering.
If you're an engineer in that scenario, you're either running, helping clear debris, or giving first aid/supplies. Your computer is nonsense at that point and yes it's a sign of a problem if you are clinging onto your devices in such a disaster scenario.
EDIT: Just re-read, I might have gotten you confused with someone on a different thread entirely about Kubernetes... Maybe I typed on the wrong tab, oops. Your comment is about data not uptime.
And how are you currently preparing your company against a solar flare?
> How many times have you known this to happen?
That's irrelevant, if it can happen, it will happen, and it's too late once you've lost your data. Maybe for some businesses, data isn't important, but I don't know of many?
