Synology Hybrid ShareBETA

Synology Hybrid Share connects your on-premises Synology NAS with Synology C2 cloud storage, keeping all data in the cloud while retaining only frequently used data in a local cache on the NAS for fast and low-latency access.

Backed by unlimited cloud scalability

Imagine if you can manage resources efficiently while scaling your business. Hybrid Share is perfectly integrated with our public cloud service C2 Storage, delivering a hybrid-cloud solution that combines key cloud storage benefits including availability, flexibility, and scalability —  all in one Synology NAS box.

A hybrid approach for Synology NAS

You can easily yet substantially expand the value of your Synology NAS infrastructure with low upfront costs.1 Start scaling storage on-demand and on a pay-as-you-go basis, and improve workforce productivity through global file sharing. Achieve more without any compromises of data security or system performance!

Multi-site file sharing

Instantly sync cloud-managed data to each NAS and access them as local cached data, reducing on-premises storage footprint, minimizing bandwidth usage, and cutting associated costs.

Instant data access

Cloud-based data are accessible on your NAS immediately upon the connection of a Hybrid Share folder. This also eliminates the long hours typically needed for data migration or recovery.

Cache data at local needs

Fulfill different system and workplace needs effortlessly. Mount the same Hybrid Share folder on different NAS and customize the maximum cache size for each NAS, ensuring fast data access and optimal storage deployments on each site.

Access cloud data at LAN speeds 

The data cached on your NAS enables fast and native file access experiences via file protocols (e.g., SMB, AFP, NFS, and FTP) and web browsers (e.g., File Station) — even for offline access.

As private as it should be

Your data are encrypted using end-to-end AES-256 standard at all times, no matter whether stored on the public cloud or in transit. Private keys are generated client-side and never get passed to Synology. Only you, the holder of the key, can decrypt and access your own data.
