I use a program called Synchronize It!

It can keep folders, computer etc in synch based on latest file date, can copy in either direction, only copies later/updated files, has lots of useful filters and more.

Compares by Date & Size, Date or Content, Content, Size Only

It keeps all my music drives in synch, and I use it for backup for off-site storage etc.

It also has compare tools features for comparing the content of files.
