Combine this with docker export / import and you got yourself an easy way to copy images between servers :)

If you still have the setup up and running, throw this in the mix:

  rsync -a -e 'ssh -c arcfour' source dest:destpath

and

  rsync -az -e 'ssh -c arcfour' source dest:destpath

still encrypted! The latter enables compression, but I've found it slower when dealing with several small files (ex: source code files)
