> It would be nice if I can get the files into git that I can save to a private github repo

It's just a directory of markdown files. Nothing preventing that directory from being a Git repo. Lots of people use it that way (or with Syncthing, Dropbox, or whatever).

Since it's just markdown files, using a fit repo to sync it is trivial. There's even an obsidian plugin to automatically commit/push in regular intervals (i.e. every 30 minutes).

I've been playing with this app for a few minutes, and it does appear to save everything in plain text files, so adding it to git would be straightforward.

I'm currently saving into a dropbox folder, which gives me automatic syncing.

I do exactly that. git init and git push and you’re done.

I setup a cron job to git add ., git commit, and git push everyday at 3am, so that I don’t have to think about it at all. It works great.

Can you explain your setup a bit more in detail? I never thought about using git as storage

Dokuwiki is easy to use, mature, stores its data in plain text files (no database needed, or supported). It also shows backlinks out of the box.
