Data Backup

Handy tips for protecting your files

Keep your data safe and sound with these backup and security solutions

Hard drives fail. Computers get infected by viruses. Mobile devices break or disappear. Ask yourself, if one of these accidents happened to you, would your files be safe? Be it your home videos or business documents, your data deserves a great protection solution, so your files — your memories — stay with you forever.

Regularly back up your devices

With its large and scalable storage capacity, Synology NAS is the logical choice for backing up files on all your devices, whether it’s a Windows, Mac, or Linux computer, or mobile devices. You can back up specific folders on your computer in real time with Cloud Station, or take advantage of native support for Apple’s Time Machine, and other third-party backup applications. If anything happens to your devices, your files will be safe on Synology NAS.

Regularly back up your devices

Back up your data to an off-site location

When it comes to protecting important files, businesses can never be too safe. Unexpected events like thievery or a natural disaster can wipe out your data infrastructure, leaving your business paralyzed. To prevent such situations, Synology NAS lets you easily back up data to an off-site destination, such as another Synology NAS or rsync-compatible servers.

Back up your data to an off-site location

Store archived data in the cloud

For home users or small businesses, purchasing dedicated equipment for off-site backup might be impractical. For such users, Synology NAS makes it easy to back up data directly to various cloud storage services, such as Amazon S3, Glacier, Microsoft Azure, OneDrive, Google Drive, or Dropbox. Keep commonly used files on your Synology NAS for guaranteed fast access, while archiving old files in the cloud.

Store archived data in the cloud

Manage drives and mirror data with SHR

No matter the brand or model, there’s always a chance a drive might fail, possibly resulting in permanent data loss. For models with two or more hard drive bays, Synology Hybrid RAID (SHR) storage technology automatically manages storage capacity and mirrors your data across each drive. That way, your files remain readily accessible, even if a drive breaks or dies.

Manage drives and mirror data with SHR

Defend yourself with modern security tools

Your data should be safe and private — no questions asked. Because the Internet is full of prying eyes, Synology NAS is equipped with robust security tools to prevent malicious attacks and make sure your data doesn’t fall into the wrong hands.

High Availability

Unexpected service disruptions can cost your company big as well as cause logistical headaches for your IT department. Synology High Availability (SHA) alleviates these issues and delivers a hassle-free method to mirror data and maximize your service uptime. SHA is available on select Synology NAS.

How does it work?

SHA combines two Synology NAS servers into one high-availability cluster (or HA cluster). One server assumes the role of active server, while the other becomes a standby passive server. The active server handles all data requests and services, while everything is continuously replicated to the passive server. This provides a complete hardware and data redundancy solution in case of unforeseen accidents. Watch the video to learn more about SHA.


Real-time protection

Real-time protection

With the real-time data mirroring mechanisms, SHA makes sure your data is safely stored on another physical unit. This real-time replication ensures that in the event of hardware failure, all data can be accessible soon after.

Automatic fail-over

The two servers communicate via a Heartbeat connection. When the active server becomes unavailable, the passive server automatically kicks in and takes over all services without human intervention. The smooth transition ensures maximized service uptime so the clients won't even notice something went wrong.




Normal situation - left server is active

Active server is experencing an error

Right server becomes active and start re-syncing


Robust HA solution

Synology High Availability makes the cluster robust and stable for resource-demanding services, such as storage for virtualization. With real-time data replication, the passive server can resume the majority of running services whenever needed.

  • Virtualization ready
    Synology NAS is an ideal target for accessing virtual machines through iSCSI. SHA ensures stored virtual machines are constantly available. Certified for VMware, Citrix, and Windows Server, a Synology NAS also benefits from a user-friendly LUN manager for rapid creation, cloning, or removal.
  • Highly available application server
    Intuitive application serving is an essential part of the Synology experience. Whether it's file services, web service, or Cloud Station, most Synology packages and built-in services are compatible with SHA to maximize uptime when hardware failure occurs.

Additional features

The user-friendly design reduces the effort required for setting up a powerful HA cluster. The quorum server further enhances the stability when the passive server needs to take over the services.

  • Hassle-free installation and maintenance
    The intuitive user interface makes SHA super simple to set up and get running. With its handy, built-in management tools, you can easily monitor the HA cluster and perform maintenance, without needing to acquire additional technical knowledge.
  • Quorum server ready
    The timing for the passive server to take over the main operation is critical. Quorum Server plays the key role in reducing the occurrence of split-brain effectively, thus maximizing service continuity and data consistency.

iSCSI Storage

Synology provides storage solutions for virtual environments of high performance and reliability. These solutions ensure the continuity and efficiency of business for large and demanding enterprises.

Certified storage

Synology storage solution supports most of the productivity-enhancing virtualization solutions, such as VMware® vSphere™, Microsoft® Hyper-V®, Citrix® XenServer™, and OpenStack Cinder.

Certified storage

High performance

With a small upfront investment, businesses can benefit from significant server performance enhancement. With the SSD cache write mode, data is first written on the SSD then flushed back to hard drives afterward. A single SSD cache mounted volume can consist of up to 12 SSDs, so you can simply accelerate read and write speeds by adding additional SSD cache on heavy load application servers that require high random IOPS.

High performance
