I’m still distrustful of cloud storage - call me a fossil - so I do my own. I have a NAS drive that’s in raid 0 mode, so the two physical drives are always shadowed: if one fails, I get an alarm, can unplug and replace it with zero down time. All the devices in the house have access to the NAS, so we use it instead of the local drives for anything important. Then I have an external USB drive that I keep in a drawer at work, and I bring it home every month or so and copy the NAS to it.
Probably not a perfect solution, but seems to work.
