I've had Google photos eat ~12 months worth of pictures, I don't really trust anyone to keep my data safe.

Logseq has been fine for me over several years, but it also makes it extremely easy to auto-commit to git.

Logseq's git auto-commit is a great insurance policy and should make recovery a breeze.

Ah, those appear to be entirely multi-device-sync problems. (I use logseq with git-autocommit for storage and backup - but since the multi-node sync stuff wasn't available for self hosting anyway, I've never tried it, and thus dodged the problem entirely. Obviously for a lot of people multi-device use is the entire point, but for some of us, logseq is "just an editor"...)
