Part 1. QNAP Data Loss 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.
Common Data Loss Causes |
Recovery Methods |
| Accidental Deletion | Recover From the QNAP Recycle Bin (If Enabled) |
| Recycle Bin Disabled/Emptied | Recoverit NAS Recovery – A QNAP Data Recovery Tool for All Occasions |
| Formatting Without Backup | |
| RAID or File System Failure | |
| The Qlocker Ransomware Attack | Recover Files From Qlocker Ransomware Attack With QNAP QRescue |
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.
QNAP deleted file recovery is the process of restoring lost or corrupted data from QNAP storage systems. These systems use multiple drives to store data. If files are deleted or a drive fails, the data isn't erased right away—it stays until new data replaces it. Recovery tools scan the storage and help rebuild lost files.
QNAP NAS recovery deals with various data loss issues. Files may be accidentally deleted, hard drives can fail, or the RAID system may get corrupted due to power outages.
Firmware updates might also cause crashes. Each problem needs a different recovery method, but acting fast helps prevent permanent data loss.

FAQ
-
Q1: Can I recover data from a completely dead QNAP NAS?
Yes, recover QNAP data is possible even from dead NAS systems. Remove the hard drives from the failed unit and connect them to a working computer. Use specialized QNAP recovery software like Recoverit to scan the drives directly. The recovery success depends on whether the drives themselves are still functional, even if the NAS unit has failed completely. -
Q2: How long does QNAP data recovery typically take?
QNAP data recovery time varies based on drive size, damage level, and recovery method used. Simple file recovery might take 1-3 hours for smaller drives. Complex QNAP NAS recovery from failed RAID systems can take 8-24 hours or more. QNAP recovery software with faster scanning algorithms like Recoverit can reduce recovery time significantly compared to basic tools. -
Q3: Is it safe to attempt DIY QNAP data recovery?
DIY QNAP file recovery is safe for logical failures like accidental deletion or file system corruption. Use reliable QNAP data recovery software and never save recovered files to the same drives. However, avoid DIY attempts if you hear unusual drive noises or suspect physical damage. Recover data from QNAP drive operations should be left to professionals when hardware failure is involved to prevent permanent data loss.
