Ubuntu: rSync without git subdirectory

Previously I blogged about a good backup/sync tool rSync.

While using it, I faced some problems. It replaced my .git repository and there by affected my git repo settings.
I found a way to exclude sync'ing some files/folders. For this we have to use --exclude option. To exclude git sub-directory:

rsync -a --exclude='.git/'

 And to include some specific files, (Eg: 'c' files)

rsync -a --include='*.c/'
