"you would typically use Smart Update to update a backup"

Dave please help me with this;

I've ALREADY used "Copy newer files" to a VIRGIN Hard Drive. Have I done the WRONG thing? I've already looked at the copied files, and everything's there. So what have I missed?

Can't I just continue and use Smart Update to update files as I go along?

If 'Smart Update' is all you should be using, then what are the other options for?

Thanx
Mike
