Coping form one HD to another

[zillah]

I have got two hard disks (A, and B ) for archiving, and I want to copy from hard disk A to hard disk B, only the files that are not exist in hard disk B (instead of coping the entire hard disk A to B, which takes long time), what should I do to achieve this, do I need to use third party program ?
