Synology NAS Data Recovery: Tips and Techniques


Data loss can be a significant challenge when dealing with a Synology NAS system. However, with the right tips and techniques, you can increase your chances of a successful data recovery. This article will explore various methods and provide practical advice to help you recover your valuable data from a Synology NAS device.

1. Check DiskStation Manager (DSM)

Before attempting any data recovery techniques, it is essential to ensure that your Synology NAS is running the latest version of DiskStation Manager (DSM). Upgrading to the latest version may introduce new bug fixes and improvements that could potentially assist in recovering lost data.

2. Utilize Data Recovery Software

In cases where data loss occurs due to accidental deletion, software-based data recovery tools can be quite helpful. Synology offers its own built-in data recovery tool called "File Station" which allows you to recover deleted files from the Recycle Bin. Additionally, third-party software tools such as EaseUS Data Recovery Wizard and Recuva can be employed for more advanced recovery scenarios.

3. RAID Configurations

If you are using a RAID configuration on your Synology NAS, it is crucial to understand the impact it has on data recovery. RAID levels such as RAID 0 offer increased performance, but provide no fault tolerance, whereas RAID 1 and RAID 5 offer data redundancy and are better suited for data recovery purposes. Ensure that you have a good understanding of your RAID setup and consult the appropriate documentation when attempting to recover data from your NAS.

4. Professional Data Recovery Services

In situations where all other recovery methods fail or when dealing with critical data, it may be necessary to seek professional data recovery services. Companies specializing in data recovery can utilize specialized hardware and expertise to recover data from damaged or corrupted Synology NAS devices. Be prepared for potential higher costs and longer turnaround times when opting for professional data recovery services.


Recovering data from a Synology NAS can be a complex process, but with the right techniques and resources, it is possible to retrieve valuable information. By following the tips outlined in this article, such as upgrading DSM, utilizing data recovery software, understanding RAID configurations, and considering professional services, you can maximize your chances of a successful data recovery from your Synology NAS device. Remember to always have a backup strategy in place to prevent future data loss.
