Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like QNAP often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Are there any known issues with specific anti-virus software that can result in data loss on NAS QNAP Turbo Station TS-470 / TS-470 Pro devices?

Yes, there have been reports of specific anti-virus software causing data loss on QNAP Turbo Station TS-470 / TS-470 Pro devices. One such example is the Avast antivirus software. In some cases, when scanning files on the NAS, Avast may incorrectly identify certain files as infected and quarantine or delete them, resulting in data loss. It is always recommended to carefully research and test any antivirus software before deploying it on your NAS device to avoid potential data loss issues.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS Turbo Station TS-470 / TS-470 Pro can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

  1. Power off the NAS and disconnect it from the power source.

    WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

  2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

  3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

  4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

Refer to your router's documentation for specific instructions on how to set up port forwarding.
    4. Configure DDNS (Dynamic DNS): If your internet service provider assigns you a dynamic IP address, you will need to set up DDNS to associate a domain name with your Turbo Station's IP address. This way, you can access it using a consistent address. QNAP provides a built-in DDNS service, or you can use a third-party service like No-IP or DynDNS.
    5. Enable HTTPS: For secure access, it is recommended to enable HTTPS on your Turbo Station. Go to "Control Panel" > "System Settings" > "Security" > "Certificate & Private Key" and follow the instructions to generate and install an SSL certificate.
    6. Set up VPN (optional): If you prefer a more secure connection, you can set up a VPN (Virtual Private Network) on your Turbo Station. QNAP supports various VPN protocols like OpenVPN and PPTP. Refer to the QNAP documentation for instructions on setting up VPN.
    7. Access the Turbo Station remotely: Now that you have set up the necessary configurations, you can access your Turbo Station's files remotely. Open a web browser on your remote device and enter the DDNS address (or the external IP address if you don't have DDNS) followed by the port number (e.g., https://yourdomain.com:443 or https://your-external-ip:443). Log in using your Turbo Station's administrator credentials and navigate to the File Station to access your files.

    Note: Ensure that you have a strong password for your Turbo Station and consider enabling two-factor authentication for added security.

  • Are there any specific security measures that need to be implemented to ensure safe file access on the NAS QNAP Turbo Station TS-470 / TS-470 Pro from a remote location?

    Yes, there are several security measures that can be implemented to ensure safe file access on the QNAP Turbo Station TS-470 / TS-470 Pro from a remote location. Here are some recommendations:

    1. Enable HTTPS: Use secure HTTPS (HTTP over SSL) protocol for remote access to encrypt the communication between the NAS and the remote device. This prevents unauthorized interception of data.
    2. Set up a VPN: Create a Virtual Private Network (VPN) connection to securely access the NAS. A VPN encrypts the entire network traffic between the remote device and the NAS, providing an additional layer of security.
    3. Use strong passwords: Set strong, unique passwords for all user accounts on the NAS, including the administrator account. Avoid using common or easily guessable passwords.
    4. Enable Two-Factor Authentication (2FA): Configure 2FA for user authentication. This adds an extra layer of security by requiring a second form of verification, such as a code generated by a mobile app or sent via SMS, in addition to the password.
    5. Enable IP blocking and firewall: Configure the NAS to block IP addresses that repeatedly fail login attempts or exhibit suspicious behavior. Also, enable the built-in firewall to filter incoming connections and allow only necessary services.
    6. Regularly update firmware: Keep the NAS firmware up to date with the latest security patches and bug fixes. Regularly check for firmware updates provided by QNAP and apply them promptly.
    7. Enable network access restrictions: Configure the NAS to allow access only from specific IP addresses or IP ranges. Restricting access to known and trusted IP addresses helps prevent unauthorized access.
    8. Disable unnecessary services: Disable any unused or unnecessary services on the NAS to reduce the attack surface. Only enable the services that are required for remote file access.
    9. Regularly backup data: Implement a regular backup strategy to ensure that important data is backed up and can be restored in case of any security incidents or data loss.

    It is important to note that these recommendations are not exhaustive, and additional security measures may be required based on your specific requirements and environment. It is always advisable to consult the QNAP documentation and seek professional advice to ensure the best security practices are implemented.
