To copy data from one filesystem another, preserving hard links, I use:

  rsync  -avxSHW  /source-dir/  /target-dir

  -a   same meaning as for "cp" i.e. recurse and copy metadata
  -v   be verbose
  -x   do not cross filesystem boundaries
  -S   handle sparse files
  -H   handle hard links
  -W   only copy whole files

  Trailing slash on source-dir makes it copy *contents* of directory
  rather than directory itself.

It only copies changed changed files.

Be sure to use version 2.5.2 or higher of rsync.
