"It was also when I discovered you can reinstall macOS without losing any data."

I discovered this as well - nice surprise!

I've switched to (almost) all Win10 boxes at my residence, except for one 2014 15' rMBP. The Windows machines have the freeware 'Veeam Agent for Microsoft Windows' connected to an internal 3.5' 1TB drive (or 2.5 500GB drive for the two laptops that had optical drives and were removed and replaced with a 2.5 HDD caddy), that isn't running the OS. The OSS/C:\ is on an SSD.

Finally, the Windows machines are backed up via CloudBerry Labs Desktop Edition to Backblaze B2, in case the house burns down.

(I wish there was a product to remotely store time machine files, but based on the linking structure, I don't think this is possible? Carbon Copy Cloner is nice, but I wish I had incremental images)
