It's always been a fraught experience, especially if you're relying on someone else's algorithms to give you peace of mind.
The most recent experiments were using Evernote, later Nixnote (because Evernote didn't care about anyone using free software operating systems) I've now moved to a breathtakingly basic platform of Google Keep + script that reliably syncs between several devices, and allows me to pull in all my notes nightly, pop them into git, and propagate to 3 hosts / 2 sites. The same server pulls in and archives my Trello boards nightly, along with a bunch of other more mundane backups.
I've never felt so relaxed about my data.
