I use an external hard drive that runs a backup nightly, and after the local fires, I'm buying a second one and am intending to rotate them out every six months, with the extra one being kept by my sister (about 100 miles away). The six months between drive swaps, I will also back up any new files to the cloud. Then when I swap the drives, I will clear my cloud storage and start fresh. (I have way too much data to keep it all on the cloud and am not willing to pay for additional storage.)
Odds of both of us losing our homes at the same time is pretty slim. But I might also put a third hard drive in a safe deposit box, I haven't decided yet.
I use Seagate external drives; I have a 4TB backup drive that cost less than $100. (Amazon carries them.) I like them because they're small, have a good reputation, and come with built-in backup software that is really easy to configure. Plus they come in a pretty blue that I like. LOL
