File Server

Store and access files from all your devices, and protect them with smart versioning. Sort, manage, share, and sync your data across locations.

A private cloud for all your devices

Store, sync, and access data from any device, wherever you are with Synology’s private cloud solution. Sync data between different platforms and devices, and access your files through mobile apps, desktop clients, and a browser-based interface. Leverage smart versioning to back up important data via desktop and mobile applications. Learn more

Dependable and secure network storage

Use shared folders on your Synology device as reliable storage available from anywhere on your local network over all common protocols (SMB/NFS/WebDAV/FTP). Protect your files against accidental changes and removal or even malware attacks with built-in snapshot technology and other backup options.

Access files from anywhere

Sort, manage, and share your files

Rely on our file, photo, and multimedia management apps to sort your data by metadata, filters, and labels. Safely share files and folders with family, colleagues, or business customers thanks to granular access and sharing permissions. Create convenient sharing links and secure shared files with expiration dates and individual passwords. Let friends or clients review photos remotely and give easy feedback through star ratings. Learn more

Sync files and folders between sites

Benefit from two efficient ways to keep files and folders synchronized between different locations — such as your home and your business, or teams in different countries. 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.

Manage and share files

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. Learn more

Make local backups of your cloud apps

Protect business Microsoft 365 and Google Workspace accounts by maintaining complete offline copies of your crucial information and configurations with Active Backup for Microsoft 365 and Active Backup for Google Workspace.

Back up documents and multimedia

Set up backup tasks to protect important folders on your PC and macOS device with Synology Drive. On your mobile device, automatically save another copy of the photos and videos you take, and easily organize and share them through Synology Photos.

Back up all your devices

Back up your NAS to multiple destinations

Protecting the data on your Synology system, and your server itself, means storing frequent emergency copies to multiple locations. Built-in tools in Synology DSM let you efficiently back up files, folders, or your entire system from your device to remote servers, external drives, or Synology and third-party cloud storage, with space-saving deduplication technology reducing total backup sizes, and customizable backup and retention schedules for maximum flexibility.

High-frequency protection with snapshots

Take point-in-time snapshots of shared folders and LUNs at intervals of down to 5 minutes to protect against data loss, accidental deletion, or malware attacks. Set a custom retention schedule and roll back files and VMs to a version that is unaffected. Learn more

Protect your Synology system

Smart Surveillance

Transform your Synology device into a full-featured video management system for a wide range of compatible IP cameras.

Notes:

  1. Performance figures are obtained through SMB sequential throughput tests using Windows Server 2016 Datacenter on a DS1522+ with a Synology 10GbE NIC and HDD. Actual performance may vary depending on the testing environment, usage, and configuration. See performance charts for more information.

  2. PCIe add-in cards, expansion units, and storage drives are sold separately. Refer to the compatibility list for compatible devices.

  3. Based on internal processor benchmarks between DS1522+ and the prior-gen DS1520+. Actual performance may vary depending on hardware and software configuration, workload, and testing environment.

  4. Synology SNV3400 series M.2 NVMe SSD drives can be installed through the built-in M.2 slots to enable SSD caching or create SSD storage pools. Drives are sold separately.

  5. Storage figure calculated based on a RAID 5 configuration. Total storage capacity may vary depending on hard drives used and RAID configuration.

  6. C2 Storage for Hyper Backup and Hybrid Share requires purchase of an eligible annual or monthly subscription. A free trial is available for each newly registered account.

  7. Surveillance Station includes 2 free licenses. Connecting more cameras and devices requires additional licenses.  Learn more
