Hello @Andy
I have heard about that, but other forum posts indicate that this would not work well in our case. From https://forum.syncthing.net/t/how-to-properly-set-up-one-way-syncing-from-windows-folder-to-linux-box/15818:
Syncthing is not designed for one way syncing. You can use a send only or receive only folder types, but that still requires that the files are not touched in any way on the receiving side, as you’ll end up with local changes which will effectively stop the process.
I believe there are other posts about it as well.
Perhaps things have changed in regards to this behaviour?
