Best Answer

I fix my problem after trying and searching for 3 hours... the solution that work for me : Select le source disk->get info->sharing and permission and make sure sportlight, admin, and (me) are READ+WRITE, unlock, and apply to all enclosing....

after some time (applying to enclosing) restart... and the time machine backup will work :-)
