How to recover data from NAS QNAP Turbo Station TS-470 / TS-470 Pro

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.

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

Although NAS Turbo Station TS-470 / TS-470 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.

    To remotely access files on the QNAP Turbo Station TS-470 / TS-470 Pro from a remote location, you can follow these steps:

    1. Set up your QNAP Turbo Station: Connect the Turbo Station to your network and configure it according to the manufacturer's instructions. Make sure it has internet connectivity.
    2. Enable File Station: Log in to the Turbo Station's web interface using its IP address and administrator credentials. Go to "Control Panel" > "Applications" > "File Station" and make sure it is enabled.
    3. Set up port forwarding: Access your router's settings and configure port forwarding to forward the necessary ports (typically TCP port 8080 for HTTP and TCP port 443 for HTTPS) to the internal IP address of your Turbo Station. 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., 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.

  • Can you provide recommendations or best practices for optimizing file access speed when accessing files on the NAS QNAP Turbo Station TS-470 / TS-470 Pro from a remote location?

    Here are some recommendations and best practices for optimizing file access speed when accessing files on the QNAP Turbo Station TS-470 / TS-470 Pro from a remote location:

    1. Use a high-speed internet connection: Ensure that you have a fast and stable internet connection with sufficient bandwidth to handle the file transfer speeds you require.
    2. Enable and configure Link Aggregation: If your NAS and remote location support Link Aggregation, enable and configure it to increase the network bandwidth and improve file transfer speeds.
