Preventing computer hacks

Is there such a thing as a computer system that cannot be hacked into? When I read about major computer systems getting hacked and losing all sorts of information I wonder if there is such thing as a computer system that cannot be hacked. If so, why isn’t everyone using such a system? Also I read about computers whose data has been frozen because of demands for ransomware. I do an image backup of my computer every night (Macrium Reflect) and download the image to an external, portable hard drive. If something goes wrong my computer, I can restore the most recent image. And I’ve had to do this at least 6 times in the last 18 months. Always get a perfect result. Why don’t corporations and others who have computer systems back them up and store the backup off-site? When they get a ransomware demand, can’t they re-format the system and then transfer the saved image.

A non-hackable computer is one with no connection to the outside world, except for power. Which means there isn’t such a beast.

Macrium (V7) has an anti ransomware option that prevents prevents modification of backup files by anything except Macrium. Do you use it?

One has to realize the extremely different sizes of businesses and their computer systems, ranging from a few desktops and/or laptops all the way to thousands of desktops and laptops spread across numerous counties, states, countries, and, across numerous time zones.  While you very wisely backup your computer onto an external USB HDD, many corporations have multiple networks, multiple servers, multiple OSs, and so on; while many do have various forms of backup, restore, recovery, disaster recovery processes, they certainly cannot simply daily backup one computer to one external USB HDD — nor even do as I do:  backup my two laptops’s boot & OS partition onto their respective two external USB HDDs and their data partitions onto their respective single external USB HDD, normally once or twice a month on the average.
