Okay, this may be a simple error.  If you see 'unable to read 4
bytes', what this usually means is that you have a communication
error.  BackupPC is receiving data, but something is mis-configured.
My first suspect is the ssh keys.  Does the 'backuppc' user on your
backup machine have the keys it needs in its .ssh/ directory?
