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.
