As I said before there isn't one canonically correct way.  Different
people will have their favorite methods.  In this case the concept of
cloning the filesystem is the same.  One just uses tar and ssh and
other uses rsync and ssh.  Neither is wrong and neither is The One
True way.  A third person might like cpio over tar.  A forth person
might like dd.  A fifth person might like 'mondo', which I am a little
surprised that no one mentioned yet.
