Dynamic data storage for better business productivity
Hybrid Share lets businesses combine the reliability of on-premises storage with the flexibility of the cloud to enable better collaboration for distributed teams.1

Efficient cross-site synchronization
Store business digital assets on the cloud, and leverage the powerful bandwidth of C2 data centers to stream files and folders to branch offices.

On-demand storage expansion
Seamlessly expand your deployment capacity to the C2 cloud to tackle demand for additional storage while keeping your local infrastructure simple.
Designed for flexibility
With a hybrid storage approach, your team can benefit from higher availability and improved productivity through secure file sharing and synchronization.
Multi-site file sharing
Save bandwidth by uploading files only once and letting C2 Storage make them available to other sites. Local teams can request the data they need for their projects and have it downloaded to their NAS leveraging fast data center pipelines.
Reduced storage footprint
Teams retain access to the most up-to-date files without having to download large amounts of data on their local devices. Requested files are streamed, providing almost immediate access to smaller files and fast download for larger ones, limited only by the speed of your connection.
High-performance local caching
Frequently accessed data is cached on the local NAS, allowing users to access it 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



Engineered for reliability
Backed by the Synology C2 infrastructure, Hybrid Share provides convenience to distributed teams without putting their data at risk.
Digital asset protection
Leverage powerful snapshot technology to restore Hybrid Share folders to a previous version, protecting them from ransomware or accidental deletion and modification.3
Committed to data safety
Shield your business against data leaks and unauthorized access: All data handled by C2 Storage is encrypted in transit and at rest for maximum security.4
Combine with Synology Drive
Hybrid Share integrates with Synology Drive, Synology’s private cloud solution for convenient file backup and collaboration, bringing even more efficiency to your deployment. Learn more

Cross-platform data access
Access Hybrid Share folders from mobile app, desktop client, and web browser leveraging Synology Drive’s wide platform compatibility.

File-level versioning
Increase flexibility even further by enabling granular restoration for files and folders stored within Hybrid Share folders.

Intelligent bandwidth offloading
Free up bandwidth by allowing users outside the local network to open and edit files directly from C2 Storage instead of accessing them from the NAS cache.5
