How to recover data from QNAP TVS-672X 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-672X

QNAP TVS-672X 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-672X.

How to recover data from NAS QNAP TVS-672X

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 backup and recovery strategies help reduce potential data loss risks on NAS QNAP TVS-672X devices?

Yes, the use of specific backup and recovery strategies can help reduce potential data loss risks on NAS QNAP TVS-672X devices. Here are a few strategies that can be implemented:

  1. Regular Backups: Schedule regular backups of your data stored on the QNAP TVS-672X NAS device. This can be done using QNAP's built-in backup features or by using third-party backup software.
  2. Offsite Backup: It is advisable to keep a copy of your important data offsite, either by using cloud storage services or by replicating the data to another QNAP NAS device located in a different physical location.
  3. RAID Configuration: QNAP TVS-672X supports various RAID configurations. By setting up RAID, you can increase data redundancy and protect against data loss in case of a hard drive failure.
  4. Snapshot Technology: QNAP NAS devices often come with snapshot technology, which allows you to take point-in-time snapshots of your data. This can be useful in recovering accidentally deleted or modified files.
  5. Data Deduplication and Compression: Enabling data deduplication and compression features can help optimize storage space and reduce the risk of data loss.
  6. Testing and Verification: It is essential to periodically test and verify the integrity of your backups to ensure they can be successfully restored when needed.
  7. Disaster Recovery Plan: Develop a comprehensive disaster recovery plan that includes steps to recover data in case of hardware failure, natural disasters, or other unforeseen events.

Implementing these backup and recovery strategies can significantly reduce the risk of data loss on NAS QNAP TVS-672X devices and provide peace of mind for data protection.

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

Although NAS TVS-672X 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.

TVS-672X has 6 HDD slots, and it supports the following array types:

  • 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-672X 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.
