Private cloud for seamless data access
Streamlined file management and collaboration
Store, sync, access, and share data from any device, wherever you are. Work seamlessly between different platforms and devices, and access your files through mobile apps, desktop clients, and a browser-based interface. Quickly and easily roll back files in case of accidental deletion, mistakes, malware, etc., with versioning.

A private photo storage and management solution
Effortlessly back up and organize photos, videos, and other visual assets using intuitive management tools. Automatically organize your content into albums and create secure share links for stakeholders and teammates.

Boost team productivity with collaborative tools
Enhance workplace collaboration with Synology's productivity solutions. Create, edit, and share documents across teams in real time. Host an on-premises mail server to provide web-based email access while maintaining full data ownership. Additionally, stay connected through secure one-on-one chats, public channels, encrypted private channels, and group conversations.

Multi-site synchronization to empower global workflows

NAS-to-NAS synchronization
Improve workflow efficiency and team alignment across data sites with automatic one- or two-way site-to-site syncing. Files and folders are kept up-to-date across sites, so everyone stays aligned, whether at home, in the office, or across different branches — all while maintaining full control of your data.

Cloud-powered multi-site syncing
Empower global workflows with high-speed access to data from anywhere in your network. Our hybrid cloud solution caches frequently used files locally for rapid access, while less frequently accessed data is stored in the cloud, reducing your on-site storage requirements.

Sync to public cloud providers
Automatically keep data in sync between Synology NAS and major cloud providers, including BackBlaze B2, Dropbox, Google Drive, and Microsoft OneDrive. Multiple protocol support, client-side encryption, and customizable sync and bandwidth controls enable efficient storage management across various platforms.

Comprehensive data backup, protection, and recovery solutions

Take advantage of built-in backup solutions designed to protect your data with seamless 3-2-1 backup configurations.

Comprehensive and flexible Synology system backups
Protect all data, applications, and configurations on your Synology systems with comprehensive scheduled backups, including bare-metal backups, to local and remote servers, external drives, or cloud storage destinations, including Synology C2 Storage.

Tamper-proof protection with immutable snapshots
Safeguard critical LUNs and shared folders with automated immutable snapshots backed by custom retention policies. Built-in support for offsite replication further ensures robust business continuity.
