     9 Use FS with hardlink with ``cp -l``::

    10 

    11   $ cp -al  /backup/old /backup/new

    12   $ rsync -a --delete --progress /data/ /backup/new/

    13 

    14 Use FS hardlink exclusively with ``rsync``::

    15 

    16   $ rsync -a --delete --progress --link-dest=../previous /data/ /backup/new/

    17 

    18 .. note:: ``--link-dest`` accepts a relative path, it is relative to the

    19           destination directory.

    20 

    21 .. note:: Cygwin ``rsync`` implementation can use NTFS hard links with

    22    ``--link-dest`` option. Check it with::

    23 

    24      cmd> fsutil hardlink list c:\backup\new\file.txt
