rsync - Jun 2008 - unison for windows

Hi All,
I am posting this querry second time. 
What i need is-- 
{Is there any command by which I can get only the updation of file ie only the
incremental?.
Suppose I have a text file say ss.txt of 3KB in size and I have taken the 
backup of this file. Now I am making the changes in to this file(ss.txt) by 
adding 1KB of data. Now I want this 1KB data (in to a new file) when I take the
incremental.
If you please provide me the command for that by using rsync? }

Somebody gave me his precious advice for getting the objective, the person told
me to use "unison" that also use rsync protocol. This time I got the
source code for unison by following
http://www.cis.upenn.edu/~bcpierce/unison/download.html link. There are two exe
that are not executing because it needs libgtk-win32-2.0-0.dll. I am
understanding that I need to build this source code that I got for unison.
Now my problem is I am not able to build this source code. Somebody please help
me about this.

Please guide me some steps to build this code and How can I use unison for
getting my main objective.



 
Thanks
Regards
M Chauhan

Hello,

While Unison uses the Rsync algorithm, it is not itself Rsync.  I would
suggest contacting the Unison mailing list instead.

Unison won't help you here; it's just a two-way synchronization tool, as
rsync is a one-way copying tool.  If your goal is to make a series of
backups and represent small changes to large files in an efficient way,
then use rdiff-backup ( http://www.nongnu.org/rdiff-backup/ ) as Lasse
suggested.  But if you want a forward delta that you can apply to an old
copy of the file later, then use one of these tools:

- "rsync --only-write-batch=FILE" writes an rsync batch file
containing
a delta from the destination version to the source version of every file
in the run.  You can apply the entire batch file later with "rsync
--read-batch=FILE".  It's not trivial to split a batch file into
separate deltas, so you might wish to run rsync once per changed file.

- Rdiff works on one file at a time and produces a delta like those
found in rsync batch files.  You invoke the "signature" and
"delta"
steps to generate the delta and the "patch" step when you later wish
to
apply the delta.

- "diff -u" gives you a pretty textual delta if the files are text.
