rsync on Mac OS X

[Bruno Boissonnet]

Hello all,

I'm new with rsync on Mac OS X.
I'v tried to backup a project directory with the following command:
rsync -avu "${source}" "${target}"

The problem:
files into bundles are copied though they were not modified.
Furthermore, the permissions and attributes have been modified.
NOTE:
bundles are directory displayed as one file with one icon in the finder.

Source directory:
ordinateur-de-bruno-boissonnet:~/Desktop/dossier sans titre/deuxième  
dossier/Automator/Pass Random Items/build/Pass Random Items.build/ 
Pass Random Items.pbxindex brunoboissonnet$ ls -al

Is it possible to fix the problem?

Thank you.
