What does D2D mean?

Disk-to-Disk (D2D) refers to the class of backup methods in which the data is copied from a disk-typically a hard disk-to another storage medium. In a D2D system, the disk that the data is being copied from is referred to as the primary disk and the disk that the data is copied to is called the secondary or backup disk.
