Comment 2 for bug 67045

this requires minor modifications and the backend level, but do require a substantial modification on the GUI level. In order to make it easy to do this, the UI would grow a button "Exclude" or so, and would pop up a preselected items list that would already include some smart guessed files/folders a normal user might not want to backup up from his machine. You've already provided a very good use case for that, and that is not backing up vmware content in run. This should see more discussions though, feel free to add your own feedback and comments.
