How to recover data from QNAP VS-8024 NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

How to recover data from NAS QNAP VS-8024

QNAP VS-8024 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from VS-8024.

How to recover data from NAS QNAP VS-8024

Recover data from damaged RAID arrays inaccessible from a computer.

Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like QNAP also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Can the use of snapshot or versioning features on NAS QNAP VS-8024 devices aid in data recovery after data loss?

Yes, the use of snapshot or versioning features on NAS QNAP VS-8024 devices can aid in data recovery after data loss. These features allow you to create point-in-time copies of your data, capturing the state of your files and folders at a specific moment. In case of data loss or accidental deletion, you can restore the data from a previous snapshot or version, effectively recovering the lost information. It provides an additional layer of protection and can be a valuable tool in data recovery efforts.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS VS-8024 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

VS-8024 has 8 HDD slots, and it supports the following array types:

  • RAID 50;
  • RAID 60;
  • RAID 6;
  • RAID 5;
  • RAID 10;
  • RAID 0;
  • RAID 1;
  • JBOD;

NAS supports:

  • ZFS;
  • EXT4;
  • EXT3;
  • exFAT;
  • FAT32 (External Disk Only);
  • NTFS (External Disk Only);
  • HFS+ (External Disk Read Only);

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

Where are user’s files stored?

The QNAP VS-8024 network-attached storage keeps QTS (QuTS hero) operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.

      If the storage disks are not recognized by the NAS QNAP VS-8024 device, data recovery becomes more challenging. However, there are still potential options to recover the data:

      1. Check the disk connections: Ensure that the disk connections are secure and properly connected. Try disconnecting and reconnecting the disks to see if they are recognized.
      2. Use a different NAS enclosure: If the disks are not recognized by the QNAP device, try connecting them to a different NAS enclosure to see if it can detect and access the data. This can help determine if the issue lies with the QNAP device or the disks themselves.
      3. Data recovery software: If the disks are not recognized by any NAS enclosure, you can try using data recovery software designed for NAS devices. These tools can scan the disks for recoverable data, even if they are not recognized by the NAS device.
      4. Professional data recovery services: If the above methods fail, it may be necessary to seek professional data recovery services. These companies specialize in recovering data from various storage devices, including NAS devices. They have advanced tools and techniques to recover data even from damaged or unrecognized disks.

      It's important to note that attempting data recovery on your own can be risky and may further damage the disks or data. If the data is critical or valuable, it's recommended to consult with a professional data recovery service for the best chance of successful recovery.
