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 snapshot or versioning features on NAS QNAP Turbo Station TS-EC1679U-SAS-RP devices aid in data recovery after data loss?

Yes, the use of snapshot or versioning features on NAS QNAP Turbo Station TS-EC1679U-SAS-RP devices can aid in data recovery after data loss.

Snapshots are essentially point-in-time copies of the data on the NAS. They capture the state of the data at a specific moment, allowing you to revert to a previous version of the data if it becomes corrupted, deleted, or modified incorrectly. With snapshots, you can easily recover files or folders that were accidentally deleted or modified.

Versioning features, on the other hand, allow you to keep multiple versions of the same file. This can be useful in situations where you need to recover an earlier version of a file or compare different versions to identify changes or discrepancies.

By utilizing these features, you can significantly improve your chances of recovering data after a loss event, such as accidental deletion, malware attack, or hardware failure. It is important to regularly create snapshots or enable versioning to ensure you have multiple restore points to choose from in case of data loss.

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

Although the NAS Turbo Station TS-EC1679U-SAS-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 (Secure Shell) and how does it work as a network protocol?

    SSH (Secure Shell) is a network protocol that provides a secure way to access and manage remote systems over an unsecured network. It is widely used in the field of system administration and allows users to securely log into remote systems, execute commands, transfer files, and tunnel network connections.

    SSH works by establishing an encrypted connection between the client and the server. This encryption ensures that the data transmitted between the two ends is protected from eavesdropping, tampering, and other security threats. The encryption is achieved using cryptographic algorithms, such as symmetric encryption for data confidentiality and public-key cryptography for key exchange and authentication.

    When a client initiates an SSH connection to a server, the server presents its public key to the client. The client verifies the authenticity of the server's public key using a pre-established trust relationship or by prompting the user to confirm the fingerprint of the key. Once the server's identity is verified, the client generates a session key and encrypts it using the server's public key. The encrypted session key is sent to the server, which decrypts it using its private key. Both the client and server then use the session key to encrypt and decrypt the data transmitted during the SSH session.

    SSH also supports various authentication methods, including password-based authentication, public-key authentication, and two-factor authentication. These methods provide an additional layer of security by ensuring that only authorized users can access the remote system.

    Overall, SSH provides a secure channel for remote access and management of systems, protecting sensitive data and preventing unauthorized access or interception of network traffic.

  • How does the NAS QNAP Turbo Station TS-EC1679U-SAS-RP utilize SSH for secure remote access and management?

    The NAS QNAP Turbo Station TS-EC1679U-SAS-RP utilizes SSH (Secure Shell) for secure remote access and management by implementing a secure communication protocol between the client and the server. Here's how it works:

    2. Encryption: SSH ensures secure communication by encrypting all data transmitted between the client and the server. This prevents unauthorized access to sensitive information, such as login credentials or data being transferred.
    3. Secure Shell Protocol: The NAS runs an SSH server that listens for incoming connections. When a client wants to establish a secure remote connection, it initiates a connection request to the NAS.
    4. Handshake: During the connection establishment, the client and the server perform a handshake process to negotiate the encryption algorithms, exchange keys, and verify the authenticity of the server.
    5. Secure Remote Access: Once the connection is established, the client can securely access the NAS remotely using the SSH protocol. This allows users to execute commands, transfer files, or manage the NAS's settings without the need for physical access.

    Overall, SSH provides a secure and encrypted channel for remote access and management of the NAS QNAP Turbo Station TS-EC1679U-SAS-RP, ensuring the confidentiality and integrity of the data being transmitted.
