I might have been too stupid to figure it out, but I found Syncthing unusable because I couldn't set up a basic "backup" style sync. That is, anything I added to my phone folder would get synced one-way to my computer... and anything I deleted from that folder would also get synced one-way to my computer. This forced me to maintain my entire photo library on my phone, which of course is exactly what I was trying to avoid.
No, the issue is that send-only sends all modifications, including file deletion. I wanted it to only send new files, but couldn't find a way to do that.
Nice, I guess it does work. Annoying that what feels to me a basic option is hidden for power users. I don't understand what your comment is saying though?
Well that option is hidden because of the very real problems it causes in "normal" syncthing use, as explained on the page.
I'm saying that you can disregard the warning in the case of a backup system (as opposed to the normal use which is full sync between two devices that both modify files).
