Causes for Synology NAS Data Loss

Synology NAS devices are susceptible to all types of data loss typical for other data storage media, such as accidental file deletion, logical failures of the operating system, and the impacts of viruses and malicious software.

In addition, NAS storages are vulnerable to specific data loss scenarios, such as operator errors during RAID re-configuration or incorrectly adding extra disks to the NAS box, NAS software failures or flawed updates, etc.

Let’s look at the potential causes of Synology NAS drive failure with its corresponding Synology NAS data recovery solutions.

Causes Solutions
Accidental deletion Recover From Recycle Bin (If Enabled)
Recycle Bin disabled or emptied Option 1: Recoverit NAS Data Recovery (Without NAS Hard Drive Pull-Out)
Option 2: Reclaime NAS Data Recovery (Pull Out NAS Hard Drive)
Disk initialization or formatting
NAS file system corruption that leads to data inaccessible
RAID reconstruction failure
Sudden power failure or voltage fluctuations that lead to NAS server corruption
Virus attack or malware infection results in data loss

Synology offers the Recycle Bin option to store deleted files, which can be enabled for each shared folder. In this part, you will learn how to activate the Synology Recycle Bin and recover deleted files from the Synology Recycle Bin in this part.

If the Recycle Bin is emptied or the files are lost due to other reasons, you can use some third-party NAS recovery software to recover deleted or lost files from Synology NAS.

Method 1: Restore Deleted Files From Synology NAS by Using Recycle Bin

The Enable Recycle Bin checkbox is automatically selected when creating shared folders. Deleted files are kept in a subfolder created when this option is enabled. Files can be permanently deleted or recovered from the Recycle Bin. To proceed, do as follows to recover deleted files from the Synology NAS drive by using Recycle Bin:

First, the Recycle Bin must be enabled for your chosen shared folder.

  2. Go to Edit after choosing a shared folder. Then, check Enable Recycle Bin. Select Restrict access to administrators only checkbox if you want only to allow administrators access to the Recycle Bin. Press OK to save your changes.
    restore files from recycle bin

To recover a deleted file or folder from the Synology Recycle Bin:

Method 3: Synology Data Recovery Using Reclaime (Disk Pull-Out Required)

The Synology NAS data recovery process of ReclaiMe File Recovery software is relatively more complicated than Wondershare Recoverit, because you must remove the hard drives from the Synology Server first. But it does its work.

You can effectively restore the disk order, block size, start offset, and other RAID configuration parameters from the unplugged Synology NAS drive with ReclaiMe File Recovery.

Follow the steps below to recover your deleted files from Synology NAS using ReclaiMe:

After disassembling the NAS server,

  1. Pull out the hard drives from Synology NAS and connect them to your Windows PC. Remember to switch off the power when disconnecting and connecting the hard drives. Label each disk with the section it belongs in before removing them from the Synology NAS. These labels will help you similarly reassemble everything if necessary. Refuse any requests from Windows on the computer to which you have connected the disks to "Initialize disks" or even "Format" them.
  2. Launch ReclaiMe File Recovery. Most NASes use MD-Raid or LVM drivers to manage an array. ReclaiMe can break the MD-Raid and LVM control structures.
    launch reclaime file recovery
  3. Choose the NAS volume to be recovered and press Start. For btrfs-based NASes such as NETGEAR, the volume will be in the BTRFS section; for other NASes, look for it in the Linux MD-Raid or Linux LVM sections.
    select the NAS volume
  4. Wait until the ReclaiMe File Recovery brings files, then click Preview to check the recovery's quality. After purchasing the license key, copy the retrieved data to the prepared storage media.
    preview the recovered files

(ReclaiMe File Recovery Standard)

Both Recoverit and ReclaiMe NAS Recovery have a lot to offer. However, there can only be one ideal for your needs. While some may prefer ReclaiMe's broad support of Linux file systems, Recoverit provides objectively better data recovery performance and includes more extra features. Purchasing Recoverit is also significantly less expensive than the ReclaiMe.

Why should you choose Wondershare Recoverit?

Recoverit supports Windows and Mac PC, while Reclaime runs only on Windows. Furthermore, Recoverit doesn't need to pull out the NAS drives to recover data (pulling out disk may cause disk damage, resulting in further data loss). Recoverit is much more affordable than Reclaime with the same features.

Why should you choose Reclaime?

You should purchase Reclaime for advanced data recovery from Linux. Wondershare Recoverit supports the EXT4 file system and BTRFS, while Reclaime supports EXT4, BTRFS, and XFS.


Numerous factors can cause a Synology NAS drive to fail. But no worries if you accidentally delete files from a Synology NAS drive because the data can be easily recovered using the 3 methods mentioned above: Recycle Bin, Recoverit NAS Recovery software, and ReclaiMe NAS recovery software.

The comparison between Wondershare Recoverit and ReclaiMe is also included. We highly recommend Recoverit as it has a straightforward setup and is safe to use. You can recover deleted or lost files from your Synology NAS for an affordable price.
