 Backuping and restoring
=========================

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
