Cloud Sync
Seamless synchronization between private and public clouds
Cloud Sync enables you to seamlessly connect your local Synology NAS to public cloud services or on-premise storage through Amazon S3 API, OpenStack Swift, or WebDAV protocols. With Cloud Sync, you can enhance the collaboration when accessing between your local NAS and other remote cloud services, and can efficiently and easily back up data from or to public clouds.

Flexibility
Customize a synchronization strategy for each task.
Sync direction
Select one-way or two-way synchronization to flexibly backup or sync your data between your NAS and other cloud services.
Encryption and compression
Securely store and transfer your data with encryption, and reduce traffic and storage consumption with compression.
Concurrent processing
Customize the suitable number of concurrent file uploads and downloads to maximize system usage.
Selective sync
Select certain folders and filter the files you want to sync to the public cloud service or your Synology NAS, optimizing storage usage.
Schedule your sync tasks
Schedule the specific time and date to perform your sync tasks to flexibly utilize the system resources of your Synology NAS.
Traffic control
Set the bandwidth limits to prevent the upload and download traffic from interfering the general traffic on your Synology NAS.
Allow administrators to monitor and control usage
Cloud Sync allows administrators to see which user is synchronizing files to certain cloud storage services, ensuring resource usage adheres to company policy and local laws.
