Found this article about Lake City, Florida (my hometown, incidentally) that paid after a ransomware attack.
They are now going to shell out $60,000 a year for proper backup.
I also wrote this post where I estimated the cost of said proper backup for a different but similar small town. This was my estimate.
Cost of decent backup, including labor: $60,690
I don’t know what their estimate includes, but I was pretty close. Been doing this a long time. The recurring yearly costs for my solution would be a bit less, and I kind of rolled those together in a first-year estimate. Looks like Lake City is going all cloud-based so you end up trading more costs on one side or the other vs. how I would do it but they usually end up being about the same (contrary to what you’ve read, cloud is NOT cheaper).
