Answer 2

If you've lots of different instances of this problem to solve, I've had some success with Apache Ant for this kind of copy/update/backup kind of thing.

There is a bit of a learning curve, though, and it does require you to have a Java runtime environment installed.

Answer 3

I like Robocopy ("Robust File Copy"). It is a command-line directory replication command. It was available as part of the Windows Resource Kit, and is introduced as a standard feature of Windows Vista and Windows Server 2008.
