I’ll try to be as concise as possible.
Machine S shares a send-only folder with machine R1 (receive-only). I add a third machine, say R2, which happens to be in the same room as R1.
My goal is to have another copy of the folder on R2, but ideally the two machines should not download the same files twice from S. When possible, they should download from each other.
Initially I paired R2 with R1 so, more explicitly: I opened R1 config, entered R2’s device ID, shared the folder with R2… but nothing actually happened. So a few hours later I also paired S and R2, and R2 actually started syncing.
I think this may be the expected behaviour, because the folder on R1 is receive-only, so I’m not sure R2 can actually receive anything from it. is this correct?
should I change R1 and R2 to “send+receive”? I guess this should not affect S, but they may be able to propagate changes between them.
