            The FlashCopy function enables you to make point-in-time, full volume copies of data, with the copies immediately available for read or write access. You can use the copy with standard backup tools that are available in your environment to create backup copies on tape.

            FlashCopy creates a copy of a source volume on the target volume. This copy is called a point-in-time copy. When you initiate a FlashCopy operation, a FlashCopy relationship is created between a source volume and target volume. A FlashCopy relationship is a "mapping" of the FlashCopy source volume and a FlashCopy target volume. This mapping allows a point-in-time copy of that source volume to be copied to the associated target volume. The FlashCopy relationship exists between this volume pair from the time that you initiate a FlashCopy operation until the storage unit copies all data from the source volume to the target volume or you delete the FlashCopy relationship, if it is a persistent FlashCopy.

            The VolumeCopy option provides full logical drive replication within the DS4700 with enhanced data management and protection.
