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 - the ideal replacement for rsync.
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. Aspera Sync ensures 100% data integrity: users can safely move, rename, and delete files or entire directory structures, without fear of data loss.
Applications and Use Cases
Global file sharing, distribution and collaboration
- Multiple users and locations can access replicated data and share their updates, regardless of file sizes, location or distance
- Continuous updates of software builds to remote, geographically dispersed teams
- Rich media delivery from the point of ingest to remote servers for improved data availability
Real-time system mirroring
- Replicate on-demand or continuously synchronize servers in real time over the WAN, regardless of distance and network conditions
- Provision new servers or storage using a single master
- Maintain multiple copies of complete file systems for development, sandbox, quality assurance, or standby servers
File archiving and storage
- Real-time continuous data archiving of inactive data from high-speed primary storage to remote second-tier storage
Centralized, remote back-ups
- Automatically replicate business critical systems from the main datacenter to a remote backup site for disaster recovery and business continuity
- Synchronize local backups to a remote site or across two remote backup sites to ensure faster recovery times while maintaining multiple offsite copies
Server and VM migration, replication, back-up and recovery
- Minimize setup time, duplication and re-installation of new and existing systems by fast replication of servers and virtual machines
- Automate the replication of actual and virtual servers over wide area networks

Unrivaled Aspera performance
- Built on Aspera fasp™ technology for maximum transfer speed regardless of file size, transfer distance and network conditions
- Precise bandwidth control ensures the entire allocated bandwidth is utilized to achieve maximum transfer speeds, while being fair to other business-critical network traffic
- 100% reliable data delivery with real-time reporting of transfer progress and performance
Familiar rsync interface
- Compatible rsync command line interface shrinks learning curve
- Simplifies deployment, does not require a rip and replace
Flexible options for replication and sync of remote files and directories
- One-to-one, one-to-many, and full-mesh synchronization
- Supports both uni-directional and bi-directional synchronization in both push and pull mode between peers over WAN/LAN
- One-time replication as well as continuous synchronization
Designed for Extreme Scalability
- Highly scalable synchronization architecture supporting up to millions of files and multi-terabyte file sets
- Concurrent synchronization session architecture with support for clustering and multi-gigabit transfer speed
Efficient change detection and updates
- Locally detects changes and compares them to file system snapshot without having to check with remote systems
- Superfast scan to detect changes in scan-mode for large incremental data sets
- Quick restart after system down
- Replicates file moves and file renames on the source as a file move or rename on the target
- Robust - waits for the system(s) to become stable (i.e., detects whether or not files are still being modified) before performing synchronization
Complete Security
- AES SSH authentication
- AES-128 data encryption in transit and at rest, FIPS 140-2 compliant
- Data integrity verification for each transmitted block
Administration
- Flexible transfer and bandwidth management
- Remote sync management, monitoring, and control through the Aspera Console web application
- User account and workgroup administration, managed via either Aspera Enterprise Server or Aspera Point-to-Point when deployed as an add-on
