Another option, suggested by @schultzeworks
Most of my students never back up but a few will do it, usually with something like Time Machine. None of that will matter if your computer (and back up drive) gets lost / stolen / burned in a fire.
I even had a relative who was using a 15-year old hard drive as a ‘back-up’. Seriously? It cost me $500 and a month to get everything back … and we were lucky.
The best thing anyone can do is get a back-up service that is (1) off-site and (2) automatic. I like Backblaze . It’s $7 per month for unlimited data. Yup, you read that right. Seven bucks. Unlimited. Automatic.
