Ask HN: What's your backup strategy in 2018

I have a number of different machines and devices: Android phone, multiple Macbooks, a Windows Desktop and a Linux NAS. I'm having trouble coming up with a comprehensive backup plan.

At the moment, I sync everything with Resilio (sync is another question). After that, I take time machine and Carbon Copy Cloner backups of my primary Macbooks to an external drive. I also run Back blaze on the Macbooks.

I'd love to have a more comprehensive plan in place so I'm interested to hear how everyone is handling backup?
