Bacula Windows backup

FileSet {
  Name = "Full Set"
  Include {
    Options {
      signature = MD5
    }
#    File = "F:\home"
#    File = "F:\\home\\file.bkf"
     File = "F:\\home"
 }
  Exclude {
    File = "C:\\temp"
  }
}

On windows, I am not able to have my files backed up unless I mention explicitly the files I want!!
Any Idea?

Regards,
