D2D2T
Short for disk-to-disk-to-tape, D2D2T is an archiving device where data is first backed up on a disk system, but then is spooled to a tape or an optical storage system. The D2D2T device can help eliminate data loss issues companies experience with tape drive or tape failure. Using a D2D2T system of backup keeps a copy of the data on-site for faster retrieval but also enables you to keep tape copies off-site for disaster recovery purposes. D2D2T devices may be appliances, virtual tape or disk libraries.
