how to check if the restored and original are the same

[zhicheng wang]

Dear all

does anyone know how to verify if two directories are
the same: 

say for testing purposes, we backed up a directory of
200GB in size. then we restored it to another place.
how do i know the restored and the original are
identical?

thanks
cheng
