synchronize usb drive with laptop in linux

below is the command i used to synchronize the contents of my usb thumbdrive with a shared directory on my computer

>rsync -Cavz --delete /media/usbdrive/ /share/syncDir/
     -C == excludes cvs directories
     -a == archive, preserves pretty much everything recursively
     -v == verbose
     -z == compresses data, only necessary when dealing
          with a remote connection
     --delete == deletes files at the destination that are not at the
          source, read man page for more control
     --dry-run == print result to stdout without actually executing
          the sync
