   rsync cannot "backup" something it doesn't know about or isn't   
   changing... likewise your command shouldn't have deleted "extratest"

   NOTE -- the deleted file went into "2temp/elsewhere", because of the   
   behavior of --backup-dir:   
      
       Note that if you specify a relative path, the  backup  directory   
       will  be  relative to the destination directory,
