ipfs was my initial idea too. It being not private is a drawback tho

You can choose refuse things from the folder/drive and you must always configure in each computer individually like the nextcloud sync client.

I was missing this feature.

I’ll read more carefully the documentation then.

Uhm I understood that Syncthing works by copying folders between machines and keeping them synchronized.

Now, what I was looking for is a software that records that, say, machine A has a file, tells that to machine B and retrieves the file only after an explicit B request.

Does Syncthing do that?
