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.

      To recover data from an encrypted NAS QNAP Turbo Station TS-873 / TS-873A device, you will typically need the following:

      1. Encryption Password: This is the password used to encrypt the data on the NAS device. Without this password, it is not possible to decrypt the data.
      2. Encryption Key: Some NAS devices may use an encryption key in addition to the password. This key is usually stored separately from the device and is required to decrypt the data.
      3. Recovery Key: QNAP NAS devices also provide a recovery key option. This key is generated during the initial setup of the device and is used to recover data in case the encryption password is lost. It is important to securely store this recovery key.

      Without the encryption password, encryption key, or recovery key, it is extremely difficult to recover data from an encrypted NAS QNAP Turbo Station TS-873 / TS-873A device. It is recommended to keep these keys and passwords in a secure location to avoid data loss.

  • Are there any specific network settings or configurations required to ensure a successful connection between the NAS and the router?

    Yes, there are several network settings and configurations that need to be ensured for a successful connection between the NAS (Network Attached Storage) and the router. Here are some of the key considerations:

    1. IP Address: Ensure that both the NAS and the router are assigned unique IP addresses within the same subnet. This can be done either manually (static IP) or automatically (DHCP).
    2. Subnet Mask: The subnet mask should be the same for both the NAS and the router. Typically, it is set to 255.255.255.0 for home networks.
    3. Gateway: Configure the default gateway on the NAS to the IP address of the router. This allows the NAS to communicate with devices outside of its subnet.
    4. DNS Server: Set the DNS server address on the NAS to the same as the router or use a preferred DNS server provided by your ISP.
    5. Port Forwarding: If you wish to access the NAS from outside your local network, you may need to set up port forwarding on the router to allow inbound connections to the NAS.
    6. Firewall: Ensure that the router's firewall is not blocking any necessary ports or protocols required by the NAS for proper communication.
    7. Network Protocol: Verify that both the NAS and the router are using compatible network protocols such as TCP/IP, SMB (Server Message Block), NFS (Network File System), FTP (File Transfer Protocol), etc.
    8. Network Speed: Check if the NAS and the router support the same network speed (e.g., 10/100/1000 Mbps) and ensure they are connected using the appropriate Ethernet cables.
    9. Firmware Updates: Keep both the NAS and the router firmware up to date to ensure compatibility and security.

    It's important to consult the documentation provided by the NAS and router manufacturers for specific instructions on configuring network settings for your particular devices.
