Rsync cannot do this [as far as I know], but there are other tools.  For 
example, if you use LVM for managing your volumes (and you should if 
you've no other volume management in use), then you can use lvcreate -s 
to create a snapshot of the volume.  This does as you desire: it provides 
an instantaneous frozen copy of the volume's content.

Be sure to remove the snapshot when it is no longer needed.  They do 
consume increasing space in the underlying storage over time.

If you use something other than LVM, then there is likely an equivalent 
to lvcreate -s.
