+=========================
+
+rsync
+=====
+
+Use FS with hardlink with ``cp -l``::
+
+  $ cp -al  /backup/old /backup/new
+  $ rsync -a --delete --progress /data/ /backup/new/
+
+Use FS hardlink exclusively with ``rsync``::
+
+  $ rsync -a --delete --progress --link-dest=../previous /data/ /backup/new/
+
+.. note:: ``--link-dest`` accepts a relative path, it is relative to the
+          destination directory.
+
+.. note:: Cygwin ``rsync`` implementation can use NTFS hard links with
+   ``--link-dest`` option. Check it with::
+
+     cmd> fsutil hardlink list c:\backup\new\file.txt
