Sync folders one or two-way between Synology devices using Synology Drive ShareSync, a free site-to-site solution. Or choose to leverage our secure data centers to store your data in the cloud, while keeping a cache of frequently accessed or manually pinned files on your DS1522+ with Synology Hybrid Share. Such hybrid cloud storage lets you access data at LAN speeds without being limited by your local storage size or bandwidth.
Multi-Layered Backup
Back up files, folders, physical devices, VMs, and SaaS applications with free solutions, and protect your NAS with built-in technologies.
Protect full endpoints, servers, and VMs
Securely back up Windows clients and servers, Linux endpoints, VMware® and Hyper-V® virtual machines, and other Synology devices. Leverage built-in deduplication technology to greatly reduce backup sizes and multi-versioning restore systems to a time point of your choice.
Make local backups of your cloud apps
