Clonezilla is smart enough to not copy free space on filesystems that 
partimage supports.

The dd and ddrescue methods, of course, copy everything, and for really 
large disks take a long time.

An rsync copy is not a clone, in the strict sense, but a copy.  A clone 
is bit-for-bit identical.  There are advantages and disadvantages to 
each method.
