The term "disk-to-disk", or "D2D", generally refers to disk-to-disk backup. With D2D, a computer hard disk is backed up to another hard disk rather than to a tape or floppy. D2D is often confused with virtual tape, but differs in that it enables multiple backup and recovery operations to simultaneously access the disk directly by using a true file system. == Typical advantages of disk-to-disk ==
* Higher speed and higher capacity, relative to tape or floppy, resulting in shorter backup and recovery windows. * Non-linear recovery of data, enabling a specific file to be restored quicker and simpler than with tape. * Lower total cost of ownership due to increased automation and lower hardware costs.
