I'll prepare for 2 separate transfers now!
install lz4 and pv on your servers.

try some transfer locally to make sure the tools work.

then you should run this line:

dd if=/dev/<your-dev-on-adele> | lz4 | pv | nc hamster.mur.at 12346
dd if=/dev/<your-dev-on-jean> | lz4 | pv | nc hamster.mur.at 12347

and I start 2 corresponding server on hamster *now*, which will store 
the streams to local files there:

/backup/images/adelejean »nc -l -p 12346 | cat > adele01.img.lz4
/backup/images/adelejean »nc -l -p 12347 | cat > jean01.img.lz4


--> the server side is up and running *from now on* and you can start 
your transfer whenever you're ready.

*note:*  the server processes will exit after your client terminates. so 
if some error occurs on your side, I will need to restart the 
server-side processes.

it is the fastest way of transferring the data via the local network (it 
is not encrypted - so only good for our local network. it would be a 
rather poor choice for across the public internet)

so long,
r
