The only reason the majority of people who have any kind of backup have it is because they use Windows 10 or 11 with a Microsoft Account so they're syncing to OneDrive, or now possibly have accidentally enabled the "Windows Backup" app, but most of them also aren't actually aware that they have such backups or understand how they work. Backups have never and will never be something that the mass of consumers will know or care about, and the companies like Samsung, Google, Microsoft and Apple will only make such a feature integrated and automatic to the minimum level possible and make it tie you to their services as much as possible. (Of course most full backup apps tie you to their image file type, too, but at least it's not integrated into the OS and other services.) Apple does at least make Time Machine really simple. Even people using Google accounts with their Android phones manage to somehow not enable backups, or don't remember passwords so they can't recover it anyway.
Technically-savvy and business IT people of course have little excuse EXCEPT for the fact that very often users will jump through hoops to avoid properly using filesystems and network storage for their data, resulting in their own computer being the only machine with a copy of critical data, unknown to the IT staff who carefully set up servers and file shares and multiple backup functionality. And the ones that use the Trash/Deleted Items /Recycle Bin folders as their "I really need to make sure I keep these files" storage location. But in a small business that is just running a bunch of PCs and doesn't really have IT, just one niche application they run on several computers, you basically have to look at that as nothing more than consumer PCs, and sometimes even when they hire IT they won't let IT do the right thing because it costs money.
