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.

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

Although NAS Turbo Station TS-EC1679U-SAS-RP 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.

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?

    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.
