These three effective methods will provide a seamless QNAP NAS data recovery procedure.
For storing vast volumes of data in a safe, central location that is accessible from any internet-connected device, the QNAP NAS is a great choice. But even with all of its benefits, the QNAP disk can still crash and have other problems that cause you to lose vital files.
Here are some helpful hints for recovering data from QNAP NAS devices using different techniques. In addition, a broad description of QNAP NAS and details on frequent data loss problems are included in this post.
Part 1: Overview of QNAP Data Loss and Recovery
Unforeseen occurrences in the QNAP Network Attached Storage (NAS) system can cause your data to become lost, corrupted, or unavailable. Examples of these events include inadvertent file deletion, disk corruption or formatting, system crashes, etc.
Can you restore lost or deleted files from a QNAP NAS device when this happens? Indeed, without a doubt. For QNAP, data recovery is feasible.
Formatting Without a Backup
Failure of the File System or RAID
Using QNAP QRescue, you may recover files from the Qlocker ransomware attack.
Formatting and Accidental Errors Without Backup
The Recycle Bin can be used to recover files or folders that you unintentionally erased from a QNAP drive (IF ENABLED). Moreover, a few customers have yet to remember the requirements before formatting a QNAP NAS drive. Not having a backup, some people format their QNAP NAS drive. This leads to a situation where data is lost.
Failure of the File System or RAID
The most recent QNAP NAS devices have a complex data storage configuration that makes many degrees of data organization possible:
RAID level : This refers to the integration of several disks into a single storage unit. To construct storage with a certain degree of fault tolerance, QNAP leverages the Linux MD driver.
The LVM level develops RAID logical volumes.
Cluster map: It converts logical volume blocks into physical blocks in addition to the QNAP features. Moreover, it is a component of an automated storage strategy that is designed to transfer often requested data to better drives and migrate active data to high-performance drives automatically.
Filesystem: The final level is where folders and files (ZFS and ext4) are kept.
Each level in the aforementioned multi-level systems has the potential to malfunction and lose data. Don’t freak out though! For this, we have answers. The greatest QNAP Recovery Tool, BLR Tools, can help you swiftly recover your data whether you formatted the drive without a backup, disabled or emptying the Recycle Bin, or experienced any QNAP disk failure.
The Attack of Qlocker Ransomware
The most recent version (16.0.0415) of the Hybrid Backup Sync (HBS) app was made available on April 16, 2021. To solve a few security concerns, new functionalities were implemented. A potential ransomware attack was reported by users on April 21.
Researchers discovered that the Qlocker ransomware is exploiting a corrected HBS security flaw to target unpatched QNAP NAS devices physically connected to the network after the first report was published.
In response, we released the Product Security News on April 22 to persuade consumers to apply all latest updates.
After determining the path, completing the investigation, the malicious remover suggests closing the questioned HBS code on the unpatched QNAP NAS.
The Qlocker Ransomware Attack manifests symptoms in three stages:
Not yet active yet infected: No anomalies were seen.
Active (encryption in progress): User files’ filename extensions will concurrently change to “.7z”. Moreover, the 7z process has an unusually high system resource level in Resource Monitor.
Following the completion of encryption, all user files with a size of less than 20 MB now have the “.7z” filename extension. On the QNAP NAS drive, there is also a ransom note (a clear text file).
We highly recommend that all users perform a manual Malware Remover scan when the QNAP NAS is online.
After updating to the most recent version, the Malware Remover checks to see if the Qlocker ransomware and the corrected HBS vulnerability are present on your QNAP NAS drive.
But the way you connect your QNAP NAS drive to the Internet also affects the overall security of the system. Consequently, QNAP’s specially created QNAP recovery tool, QRescue, might be of great assistance to users in recovering data from the Qlock Ransomware Attack.
Part 2. Take Care to Recover Up to 100% of Your NAS Data After QNAP Data Loss
Avoid trying to fix collapsing QNAP NAS drives by yourself. You risk further damaging the disk and slowing down the restoration process.
Avoid utilizing methods of trial and error. Data overwriting from using trial-and-error approaches to restore QNAP NAS data could result in permanent system failure or data loss.
Don’t attempt to rebuild the RAID if you have set up RAID on your QNAP NAS server and have lost data as a result of many disks in the RAID array failing.
When rebuilding, it’s possible that you’ll enter the wrong RAID array parameters, which may cause irreversible data loss and a lower recovery rate.
Replace the broken drive — To guard against more damage and irreversible data loss from the damaged drive, stop using the NAS system or server if you observe drive failure indicators.
QNAP Data Recovery 1 : Retrieve Deleted Files From Recycle Bin
It would be wise to examine the Network Recycle Bin option if the device is in good working order and you are unable to locate the necessary data in their original shared location.
Step 1: It can be manually navigated. Open the Control Panel first. Next, select Network Recycle Bin under Network & File Services. Next, ensure you enable the Network Recycle Bin.
Step 2: Click the Shared folder link, then look through the list for the required folder name. To examine the settings, click Edit properties. Additionally, check the box for Network Recycle Bin and press OK.
Step 3: Alternatively, you could try this method. First, ensure you turn on the recycle bin. It will contain a special @Recycle subfolder where you can recover the erased data. To restore data, right-click on it and select Recover.
