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.

Are there any recommended practices for protecting NAS QNAP VS-4016U-RP Pro devices against physical theft or unauthorized access that can lead to data loss?

Yes, there are several recommended practices for protecting NAS QNAP VS-4016U-RP Pro devices against physical theft or unauthorized access. Here are a few:

  1. Physical Security: Place the NAS device in a secure location, such as a locked server room or cabinet, to prevent unauthorized physical access.
  2. User Authentication: Implement strong and unique passwords for all user accounts on the NAS device. Enable multi-factor authentication (MFA) if supported to add an extra layer of security.
  3. Network Segmentation: Separate the NAS device from the rest of the network using VLANs or separate subnets. This helps to limit access to the device and prevent unauthorized access from other network devices.
  4. Firewall and Intrusion Detection: Enable the built-in firewall on the NAS device and configure it to allow only necessary network traffic. Consider using an intrusion detection system (IDS) to monitor for any suspicious activity.
  5. Firmware Updates: Regularly update the firmware of the NAS device to ensure that any security vulnerabilities are patched.
  6. Encryption: Enable disk encryption on the NAS device to protect the data stored on the drives. This ensures that even if the physical drives are stolen, the data remains encrypted and inaccessible.
  7. Backup and Disaster Recovery: Implement a regular backup strategy to ensure that critical data is backed up and can be restored in case of theft or data loss. Store backups off-site or in the cloud for added protection.
  8. Disable Unused Services: Disable any unnecessary services or features on the NAS device to reduce the attack surface and potential vulnerabilities.
  9. Monitoring and Logging: Enable system logs and monitor them regularly for any suspicious activities. This can help detect unauthorized access attempts or potential security breaches.
  10. User Education: Educate users about best practices for data security, such as not sharing passwords, avoiding suspicious links or attachments, and being cautious about granting access to the NAS device.

By implementing these practices, you can significantly enhance the security of your NAS device and protect against physical theft or unauthorized access that can lead to data loss.

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

Although NAS VS-4016U-RP Pro 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 VS-4016U-RP Pro. 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.

How to recover data from a QNAP

VS-4016U-RP Pro 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.

Where are user’s files stored?

The QNAP VS-4016U-RP Pro 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.

    Can data recovery from a NAS QNAP VS-4016U-RP Pro device be done if the storage disks are not recognized by the device?
    • Hetman Software
      Hetman Software 17.09.2023 20:00 #

      Yes, data recovery can still be possible even if the storage disks are not recognized by the NAS device. Here are a few steps you can take:

      1. Check the physical connections: Ensure that the disks are properly connected to the NAS device. Try reseating the disks or using different cables.
      2. Check the disk health: If the disks are not recognized, it's possible that there may be a hardware issue with the disks themselves. You can try connecting the disks to a different computer or using a disk diagnostic tool to check their health.
      3. Seek professional help: If the above steps do not work, it is recommended to contact a professional data recovery service. They have the expertise and specialized equipment to recover data from faulty disks or NAS devices.

      It's important to note that attempting data recovery on your own may risk further data loss or damage to the disks, so it's best to consult with a professional in such cases.
