Incremental backup tools in Windows 7

DeltaCopy is an open source, fast incremental backup program.
 Download GNU software DeltaCopy from:
http://www.aboutmyip.com/AboutMyXApp/DeltaCopy.jsp
I also need to install cygwin
http://www.cygwin.com/

Installing DeltaCopy server and client is straight forward. But I still have several issues:
1) When I ran "Add file" in Deltacopy client; The error message:

Executing: rsync.exe  -v -rlt -z --chmod=a=rw,Da+x --delete "/cygdrive/C/Users/jiansen/Documents/Leonie.doc" "192.168.1.47::test1/Documents/Leonie.doc"
sending incremental file list

rsync: change_dir#3 "Documents" (in test1) failed: No such file or directory (2)
rsync error: errors selecting input/output files, dirs (code 3) at /home/lapo/packaging/rsync-3.0.4-1/src/rsync-3.0.4/main.c(614) [receiver=3.0.4]

rsync: connection unexpectedly closed (5 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at /home/lapo/packaging/rsync-3.0.4-1/src/rsync-3.0.4/io.c(632) [sender=3.0.4]

The reason is I used the file Leonie.doc  from Documents directory and the server did not have documents directory (whatever directory missing) and will not create documents directory due to that I used "Add files" instead of "Add folders".
The fix method is:
Create Documents directory in server directory or define a new Virtual directory in Deltacopy server including Documents directory

"Add folder" in client is fine.

2) There is a problem for mapped network file backup, which is explained in:
http://www.aboutmyip.com/AboutMyXApp/DisplayFAQ.do?fid=29

I have to backup them manually using a command line:
rsync.exe  -v -rlt -z --chmod=a=rw,Da+x --delete "/cygdrive/C/Users/jiansen/Desktop/CAS/jiansen_dir/www_SCHS/" "/cygdrive/z/JIANSEN-PC/www_SCHS/"

or use IP or UNC (Universal Name Convention) name:
rsync.exe  -v -rlt -z --chmod=a=rw,Da+x --delete "/cygdrive/C/Users/jiansen/Desktop/CAS/jiansen_dir/www_SCHS/" "//192.168.1.73/jiansen/JIANSEN-PC/www_SCHS/"

Another backup software is Syncrify, which can be downloaded:
