Aspera Sync is a new software engine the enables highly scalable, multidirectional file replication and synchronization. Sync is designed to overcome the bottlenecks of conventional synchronization tools like rsync and scale up for maximum speed replication and synchronization over WANs, for large file stores with large file sizes. Aspera Sync reconciles file system changes with remote peers at extremely high speed (500 files per second+) on commodity hardware and does not degrade in performance with the number of files, or with WAN conditions. Built upon patented fasp transport, Aspera Sync transfers new data between peers at full bandwidth capacity, regardless of distance and network conditions (100X+ rsync over long distance and high bandwdith WANs). This could be useful to help stage large media close to different global learning centers as Duke continues to expand the reach of our campus.
