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 insufficient power supply or voltage fluctuations cause data loss on NAS QNAP TVS-472XT devices?

Insufficient power supply or voltage fluctuations can potentially cause data loss on any electronic device, including NAS devices like the QNAP TVS-472XT.

Power supply issues can lead to sudden shutdowns or improper functioning of the device, which can result in data corruption or loss. Voltage fluctuations, such as power surges or drops, can damage the internal components of the NAS device, including the hard drives where the data is stored.

To protect your NAS device and prevent data loss, it is recommended to use a high-quality uninterruptible power supply (UPS) that can regulate the voltage and provide backup power during power outages. Additionally, surge protectors can help safeguard against voltage spikes.

It is also crucial to regularly backup your data to an external storage device or cloud storage service to minimize the risk of permanent data loss in case of any unforeseen power-related incidents or hardware failures.

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

Although NAS TVS-472XT 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-472XT. 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-472XT has 4 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.

  4. At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

Where are user’s files stored?

The QNAP TVS-472XT 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.

      Yes, it is possible to recover data from a NAS QNAP TVS-472XT device that has been affected by a network attack or intrusion. However, the success of data recovery depends on various factors such as the extent of the attack, the type of attack, and the measures taken to protect the device.

      Here are some steps you can take to recover data from a compromised QNAP NAS device:

      1. Disconnect the device from the network: Immediately disconnect the affected NAS device from the network to prevent further damage or data loss.
      2. Isolate the device: Physically isolate the device from other network devices to prevent the spread of malware or further attacks.
      3. Assess the damage: Determine the extent of the attack and identify the type of malware or intrusion. This will help in formulating an appropriate recovery plan.
      4. Contact QNAP support: Reach out to QNAP support for assistance. They may provide guidance on recovery options or recommend professional data recovery services.
      5. Restore from backups: If you have regular backups of your data stored on the NAS, restore the data from the backup source. Ensure that the backups are clean and not compromised.
      6. Scan for malware and vulnerabilities: Once the data is recovered, thoroughly scan the NAS device for malware and vulnerabilities. Update the firmware and security patches to prevent future attacks.
      7. Engage professional data recovery services: If the data recovery process is complex or if you are unable to recover the data on your own, consider engaging professional data recovery services. They have specialized tools and expertise to recover data from compromised devices.

      It is important to note that prevention is always better than recovery. Implementing strong security measures, such as using complex passwords, enabling two-factor authentication, keeping the firmware up to date, and regularly backing up data, can help prevent network attacks or intrusions on NAS devices.
