Re: two kinds of people ...
The third type are those who have observed other people lose all their data without backups, and so resolve not to have that problem. And to date, I haven't. I've got all my personal stuff dating back to the 1960s. The most I've lost has been a couple hours here and there ... but always at an inopportune time, of course.
Proper backups are a vital part of properly running any computerized system. However, I can make a case for simply having multiple copies (off site is good, cloud maybe not so much) of all your important personal files being all that's needed for the average single-user/family home system. The OS can be reinstalled, your pictures and personal correspondence (etc.) cannot.
