Efficient cross-site synchronization

Hybrid Share lets businesses store large sets of data in the cloud while leveraging the powerful bandwidth of a data center to stream requested data to branch offices. Each office's Synology NAS retains a cache of the most frequently requested files to ensure fast, low-latency access for local users.1

Keeping teams connected

Keep your important shared files on C2 Storage, ready to be streamed to local Synology NAS at offices and homes around the world whenever users need them. Let employees around the world access the most up-to-date files while maintaining only a modest-sized Synology NAS at each site.

A hybrid approach

A hybrid storage approach enables your business to benefit from higher availability, scalability, and improved productivity with efficient file sharing among remote teams. Achieve more without compromising on performance or security.

Multi-site file sharing

Maintain a reduced onsite storage footprint by requesting only the data you need. Save bandwidth by uploading files once and then letting C2 Storage propagate them to other sites using its fast data center pipelines.

Cache data used locally

Keep frequently used data on your local NAS, allowing users to access files at LAN speeds. Files and folders can also be pinned manually to prevent them from being replaced by newer data when the cache is full.2

Instantly access files

Users can view all data available through Hybrid Share-enabled folders and request any files they need. Files are streamed, providing almost immediate access to smaller files like documents, and fast download of other files, limited only by the speed of your connection.
