Cloud Station ShareSync

Note: Cloud Station Server will now be succeeded by a new application, Synology Drive Server, which covers the original key functionalities. We recommend upgrading to Synology Drive Server for optimal performance and various new features. Please visit this tutorial to learn about feature differences and how to upgrade before you start.

Cloud Station is a file sharing service that allows you to synchronize files between a centralized Synology NAS device and multiple client Synology NAS devices, computers and mobiles. To seamlessly sync your data among multiple Synology NAS devices, a Synology NAS device has to be chosen as the host server, and the rest of the paired Synology NAS devices will act as client devices. Before syncing files with client devices, Cloud Station Server package is required to be installed on the host server, while Cloud Station ShareSync package has to be installed on each client Synology NAS device you want to sync with.
