Aspera Sync is purpose-built by Aspera for high-performance, scalable, multidirectional asynchronous file replication and synchronization. Designed to overcome the bottlenecks 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.

The fasp™ advantage
Unlike conventional tools like rsync, 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 as numbers of files increase, or with WAN conditions. Built upon Aspera fasp™, Aspera Sync transfers data between peers at full bandwidth capacity, regardless of distance and network conditions (100X+ over rsync) over long distance and high bandwidth WANs.

Superior to rsync
Unlike rsync and conventional replication tools which copy any new data over the WAN, Aspera Sync intelligently recognizes changes and file operations such as moves and renames, instantaneously propagating these to remote peers, avoiding what can be hours of unnecessary copy times. Users familiar with rsync will immediately recognize the similar Aspera Sync command line interface. Aspera Sync offers higher performance, without a steep learning curve.

Flexible deployment
Also, unlike unidirectional-only tools, Aspera Sync supports bidirectional and multidirectional synchronization topologies where content is changing on multiple nodes. Replication jobs can be configured to run continuously for real-time synchronization, or one-time, on demand. Finally, Sync ensures 100% data integrity:  users can safely move, rename, and delete files or entire directory structures, without fear of data loss.
