The best way to do this is with robocopy.
ROBOCOPY source destination /MIR
will mirror the source. This only copies files that are different. It will
also delete files at the destination if they don't exist at the source. I
use this for backups all the time. You can create a script (.CMD file),
create a shortcut to the script on your desktop, then double click the
shortcut to do a backup. If you don't want to mirror the source then
robocopy has a very rich set of switches that can do almost anything you
want when copying files.
