Cross-site syncing
Secure site-to site file and folder syncing
Make sure branches always have up-to-date copies of crucial documents and data available locally by syncing Synology systems one or two ways using Synology Drive ShareSync. Keep files updated across locations each time there is a change to efficiently keep all stakeholders on the same page.
Efficient cross-site syncing through the cloud
Boost syncing speeds, cut bandwidth use, and reduce your storage footprint by leveraging the powerful connectivity of our data centers. Synology Hybrid Share intelligently synchronizes data to Synology devices.6 Large or less frequently accessed files are stored on the cloud to reduce local storage requirements, while frequently used files are stored on local devices to provide users access at LAN speeds.
Backup repository
Back up files, folders, physical devices, VMs, and SaaS applications with free solutions, and protect your NAS with built-in technologies.
