How to recover data from QNAP TVS-863+ 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 TVS-863+

QNAP TVS-863+ NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from TVS-863+.

How to recover data from NAS QNAP TVS-863+

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 specific encryption algorithms or protocols impact data loss risks on NAS QNAP TVS-863+ devices?

Yes, the use of specific encryption algorithms or protocols can impact data loss risks on NAS QNAP TVS-863+ devices. Encryption algorithms and protocols are responsible for securing data and preventing unauthorized access. If strong encryption algorithms and protocols are used, the risk of data loss due to unauthorized access or data breaches is significantly reduced.

QNAP TVS-863+ devices support various encryption options, including AES-256 volume-based encryption and SSL/TLS protocols for secure data transmission. By enabling these encryption features and using strong encryption algorithms, the data stored on the NAS device becomes more secure, reducing the risk of data loss.

However, it is important to note that encryption alone cannot guarantee complete protection against data loss. Other factors such as secure password management, regular backups, and proper access controls also play crucial roles in mitigating data loss risks.

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

Although NAS TVS-863+ 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with QNAP TVS-863+. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

TVS-863+ 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 TVS-863+ 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.

      Hetman Software 17.09.2023 04:59 #

      The data recovery process from a NAS QNAP TVS-863+ device can vary in duration depending on several factors such as the size of the data being recovered, the type of recovery being performed (e.g., simple file recovery or complete system recovery), the condition of the device, and the speed of the recovery tools being used.

      In general, data recovery from a NAS device can take anywhere from a few hours to several days. It is important to note that data recovery is a complex and time-consuming process that requires careful analysis and reconstruction of the data. Additionally, if the device has suffered from physical damage or hardware failure, the recovery process may take longer as it may require repair or replacement of the faulty components.

      It is recommended to consult with a professional data recovery service or the manufacturer's support team for a more accurate estimate based on your specific situation.
