What is Disk-to-Disk Backup (D2D)?
Disk-to-disk backup is a backup type in which data is copied from a hard disk onto another hard disk. In comparison with disk-to-tape backups, D2D backup files can be accessed directly just like any disk system.
Tapes, conversely, have to be searched linearly and are not as expedient at retrieving data. Unitrends uses disk-to-disk technology to provide rapid backup and recovery of both files and full systems.
Unitrends was the first to offer true disk-to-disk data backup and restoration protection as the standard method for drastically reducing the time to capture data images. Disk-to-disk improves backup and recovery time by as much as 5 times over a tape system, and raises the effective utilization of existing server resources.
Unlike other disk systems that rely on tape simulation, true disk-to-disk allows simultaneous data backup and recovery, reducing the backup window even more.
