Aspera Sync is purpose-built by Aspera for high-performance, scalable, multidirectional asynchronous file replication and synchronization. Designed to overcome the performance and scalability shortcomings of conventional synchronization tools like rsync, Aspera Sync can scale up and out for maximum speed replication and synchronization over WANs, for today’s largest big data file stores—from millions of individual files to the largest file sizes.
