QNAP NAS Data Recovery

Here are the three efficient solutions to perform a smooth QNAP NAS data recovery process.

The QNAP NAS is an excellent option for keeping large amounts of data in a secure, central location that can be accessed from any device with an internet connection. However, despite its many advantages, the QNAP drive is not resistant to crashes and other issues that could result in losing important files.

Here, you can find some useful tips on QNAP NAS data recovery implementing various methods. This article also provides a general overview of QNAP NAS and information on its common data loss issues.

Part 1. QNAP Data Loss and Recovery Overview

Unforeseen events like accidental file deletion, disk corruption or formatting, system crashes, etc., may render your data lost, corrupted, or inaccessible in the QNAP Network Attached Storage (NAS) system.

When this occurs, can you recover deleted or lost files from a QNAP NAS drive? Yes, of course. Data recovery for QNAP is possible.

Accidental Deletion and Formatting Without Backup

If you accidentally delete files or folders on a QNAP drive, you can restore them using the Recycle Bin (IF ENABLED). Furthermore, some users still forgot the prerequisites before formatting a QNAP NAS drive. Some format their QNAP NAS drive without having a backup. Thus, it results in a data loss scenario.

RAID or File System Failure

The latest QNAP NAS devices implement a complicated setup of data storing which facilitates many levels of data organizing:

  • RAID level – This is where several disks are integrated into a single storage. QNAP uses the Linux MD driver to create storage with a certain level of fault tolerance.
  • LVM level – It develops RAID logical volumes.
  • Cluster map – Along with the QNAP features, it translates logical volume blocks into physical blocks. Additionally, it is used as a part of an automated storage strategy programmed automatically to move active data to high-performance drives while leaving not often requested data to the better drive.
  • Filesystem – The last level stores files (ext4 and ZFS) and folders.

In the abovementioned multi-level systems, each level can fail and lose data. But don't panic! We got solutions for this. Whether you have disabled or emptied the Recycle Bin, formatted the drive without backup, or encountered any QNAP drive failure, you can quickly recover your data with the best QNAP Recovery Tool – Recoverit NAS Recovery.

The Qlocker Ransomware Attack

On April 16, 2021, Hybrid Backup Sync (HBS) app's updated version (16.0.0415) was released. The new features were added to address some security issues. On April 21, users reported possible ransomware attacks. Following the release of the initial report, it was revealed that the Qlocker ransomware is exploiting a patched HBS security vulnerability to attack unpatched QNAP NAS directly connected to the network.

As an action, on April 22, the Product Security News was announced to convince users to install all recently released updates. The investigation is finished as the path is identified, and the Malware Remover advises closing the HBS code in question for unpatched QNAP NAS.

The symptoms of the Qlocker Ransomware Attack have levels:

  • Infected but not yet active: No abnormality observed.
  • Active (encryption in progress): The filename extension of user files will become ".7z" simultaneously. Furthermore, in Resource Monitor, the 7z process occupies an abnormally high system resource level.
  • Post-activity (encryption ended): The filename extension of all user files (size < 20MB) is now ".7z". A ransom note (clear text file) is also displayed on the QNAP NAS drive.

For all users, it is highly suggested to run a manual Malware Remover scan while the QNAP NAS is connected to the Internet. The Malware Remover updates its detection to the latest version and then scans if your QNAP NAS drive is experiencing Qlocker ransomware and the patched HBS weakness.

However, how your QNAP NAS drive is connected to the Internet also impacts the overall system security. As a result, to help user rescue data, QRescue, a specially designed QNAP recovery tool by QNAP, can be a big help in recovering data from the Qlock Ransomware Attack.

Part 2. Cautions After QNAP Data Loss to Recover Up To 100% NAS Data

  • Don’t attempt to repair collapsed QNAP NAS drives ALONE – Doing so may further damage the QNAP NAS drive, decreasing the speed of restoration.
  • Don’t use trial-and-error methods – Using trial-and-error methods to restore QNAP NAS data may lead to data overwriting, leading to permanent system failure or data loss.
  • Don’t reconstruct the RAID configured on NAS – If you’ve configured RAID on your QNAP NAS server and have lost data due to the failure of multiple disks in the RAID array, DON’T try to rebuild the RAID. You may have the possibility to enter incorrect RAID array parameters while rebuilding, which will result in permanent data loss and a decreased recovery rate.
  • Substitute the malfunctioning drive – If you notice drive failure signs, prevent using the NAS system/server or substitute the failing drive to protect against further destruction and permanent data loss from the damaged drive.

QNAP Data Recovery #1: Recover QNAP Deleted Files From Recycle Bin

Step 1. You can navigate it manually. First, open Control Panel. Then, go to Network & File Services and click Network Recycle Bin. From there, check the Enable Network Recycle Bin option.
