Getting started:
* Copy blocksync.py to the home directory on the remote host
* Make sure your remote user can either sudo or is root itself.
* Make sure your remote user write in the dest block device.
(root or with sudo for example)
* Make sure your local user can ssh to the remote host
* Invoke:
sudo python blocksync.py /dev/source user@remotehost /dev/dest
blocksync /dev/source user@remotehost /dev/dest
