I encrypt anything important and use Google for offsite cloud because I, luckily, only have text and a few gigabytes of images that I want the extra step of encryption for.

Everything else, media and such that's hard to replace but not important gets put on a drive and swapped out monthly to my sister's house, and my best friend's house.

Here, there's a drive on each PC with that stuff, plus whatever is on the individual PC that gets moved to those drives. I'd have to go look for which is where though. But that's five copies that I update from my main PC as I get new stuff, so they get moved around a good bit. And there's a backup that is held as a spare.

But, all my files for the stuff I write are also synced to Dropbox and gdrive hourly when I'm writing, and again at the end of a session. During each session, its autosaved every five minutes because I'm a tad lazy and don't like rewriting things I just wrote because there's a power issue out here in the boonies. UPS might be an option, but I don't always write on the same thing.

I don't like Google any more, and don't trust any of the "cloud" services as far as I can spit, but they are stable. I've never lost anything from the major services, and the free tiers are enough for my needs of important stuff.
