My first post here - Syncthing is great for what I’ve seen so far!
Would you reckon in scope if after mutual consent (could be receive-only + main host, or it could be rcv-only + all cluster participants) the changes on the receive-only folder are propagated within the cluster?
I already have a use case for such an option.
And it could be further expanded furthe with granular file control.
Off-topic and introduction /feel free to disregard/ -
I am currently designing a test implementation for “real-time” sync of a ~1.2TiB iwatched folder across WAN (over dedicated 100MBit line at a 2ms distance) containing over 3.2M directories and 2M files. The test environment is virtualised and I am studying the requirements.
These directories will have Samba running on top. All Samba shares will be accessed by ~30 hosts total. Despite that, collisions will happen very seldom.
Writes per day would come at a steady pace, totalling about 3-7GiB/day. Reads range between 10-40GiB/day with possible spikes (irrelevant to the sync).
Maximum time tolerance before is approximately one minute.
We will see how it goes. I am optimistic.
