dsync replication was designed in a way that would allow transferring the state over e.g. USB sticks, although it’s missing some code to make it actually possible. > There are trams shuttling back and forth along this road (stopping at each > station), and adding a small box (such as a weatherproofed Raspberry Pi > with a wifi dongle) to transport files up and down the road is pretty > simple. But if you do it this way and you can keep a full copy of the shared mail storage on your Raspberry, that would be possible already with dsync I think. dsync supports quick incremental updates by keeping track of the previous state between the servers. This state is saved in a file, so you could keep a different state for each different dsynced server.
