I don’t use the cloud, but I do email critical files to myself every two weeks. They’re stored offsite, safe from fire, theft, and malfunction, as long as I remember my email u/n & p/w.
Not a bad idea. I have all my important data (most important being the backups of favorites) always backed up on a USB stick and in case of disastrous situation, I can grab my wallet, my glasses, the USB stick and the 9mm and make a run for it LOL.
