Retrospect Disk-to-Disk app, WIN 8

Retrospect is Powerful and Flexible. Retrospect can transfer specific or all backups between Backup Set destinations, making it trivial to back up nightly to network-attached storage and then transfer just the most recent nightly backups to a portable hard disk for safe, offsite storage. Retrospect can stage backups to disk before transferring them to tape, ensuring that the fastest possible throughput is achieved at each stage. Disk-based backups can also be copied to tape for safe, offsite storage or archiving.
