+
−=====
+
−
+
−Emulate file transfer with ``-n`` or by longer form ``--dry-run``.
+
−
+
−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
+
−
+
−Avoid carrying permissions and other attributes with::
+
−
+
−  --no-p --no-o --no-g --no-A --no-X -O -J
+
−
+
−To show current progress::
+
−
+
−  -v  --progress
+
−
+
−To copy over ssh::
+
−
+
−  $ rsync -n -e 'ssh -l $RUSER' -r  /archive/ $RHOST:/archive/
+
−  $ rsync -n -e 'ssh -l $RUSER' -r  /archive/ $RUSER@$RHOST:/archive/
+
−
+
−To compare only based on file size use ``--size-only``. In that case ``-t``
+
−option will preserve modification time.
+
−
+
−To sync files only based on timestamps (if attributes have no sence, like on
+
−Windows OS) complete invocation cn look like (final slash in path is
+
−significant)::
+
−
+
−  $ rsync -r -t --no-p --no-o --no-g --no-A --no-X -O -J --delete --progress -v  $FROM/ $TO/
