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.

Can the use of multiple NAS QNAP TVS-2472XU-RP devices in a backup or replication configuration mitigate data loss risks?

Yes, using multiple NAS QNAP TVS-2472XU-RP devices in a backup or replication configuration can help mitigate data loss risks.

By setting up a backup or replication configuration, you can create redundant copies of your data on multiple NAS devices. This ensures that if one device fails or experiences data loss, you still have a backup copy on another device.

QNAP NAS devices offer various backup and replication features, such as RTRR (Real-Time Remote Replication), which allows you to replicate data in real-time to another QNAP NAS device. This ensures that any changes made to the data on one device are immediately replicated to the other device, minimizing the risk of data loss.

Additionally, you can set up scheduled backups or use snapshot technology to take regular point-in-time copies of your data. This provides further protection against accidental deletion, data corruption, or other issues that may lead to data loss.

Overall, using multiple QNAP TVS-2472XU-RP devices in a backup or replication configuration increases data redundancy and reduces the likelihood of permanent data loss.

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

Although the NAS TVS-2472XU-RP 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.

Questions and answers

  • What is SSH and how does it work?

    SSH (Secure Shell) is a cryptographic network protocol that allows secure remote login and communication between two computers over an unsecured network. It provides a secure channel for data transmission and authentication.

    Here's how SSH works:

    1. Client-Server Connection: The client initiates a connection request to the server using the SSH protocol. The client can be any device with SSH client software installed, while the server must have SSH server software running.
    2. Encryption and Authentication: Once the connection is established, SSH negotiates encryption algorithms to secure the communication. It uses public-key cryptography to authenticate the server and the client. The client verifies the server's identity using the server's public key.
    3. Session Establishment: After successful authentication, a secure session is established between the client and server. All data transmitted between them is encrypted to prevent eavesdropping or tampering.
    4. Command Execution and Data Transfer: The client can now execute commands on the server remotely. The commands are encrypted and sent over the secure SSH connection. SSH also supports secure file transfer (SFTP) and port forwarding, allowing secure access to remote resources.
    5. Connection Termination: When the session ends, the SSH connection is terminated, and the encryption keys are discarded.

    SSH provides a secure alternative to protocols like Telnet, FTP, and Rlogin, which transmit data in plain text, making them vulnerable to interception and unauthorized access. By using encryption and authentication mechanisms, SSH ensures the confidentiality and integrity of data transmitted over the network.

    1. Encryption: SSH uses strong encryption algorithms to secure the communication between the client and the server. This ensures that data transmitted over the network cannot be intercepted or read by unauthorized parties.
    2. Authentication: SSH supports various authentication methods, such as password-based authentication, public key authentication, and two-factor authentication. These methods ensure that only authorized users can access the system and perform administrative tasks.
    3. Integrity checks: SSH uses cryptographic algorithms to verify the integrity of transmitted data. This prevents tampering or modification of data during transit, ensuring the data's integrity.
    4. Port forwarding: SSH allows secure port forwarding, which enables users to securely access services running on remote servers through an encrypted SSH tunnel. This feature enhances security by preventing direct exposure of services to the internet.
    5. X11 forwarding: SSH supports X11 forwarding, which allows secure remote graphical applications. This feature enables users to run graphical applications on the QNAP NAS and display them on their local machine securely.
    6. Secure file transfer: SSH provides secure file transfer capabilities through the SFTP (SSH File Transfer Protocol) subsystem. SFTP ensures that file transfers between the client and the QNAP NAS are encrypted and secure.
    7. Secure remote administration: SSH enables secure remote administration of the QNAP NAS, allowing administrators to manage the system remotely without exposing it to potential security risks associated with other remote administration protocols.

    By leveraging these SSH security features, the QNAP TVS-2472XU-RP ensures that data transfer and remote administration are protected against eavesdropping, tampering, and unauthorized access. This enhances the overall security of the NAS and helps safeguard sensitive data stored on the device.
