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.

Questions and answers

  • What is SSH and how does it work?

    SSH stands for Secure Shell. It is a network protocol that allows secure remote communication between two computers. SSH provides a secure channel over an unsecured network, such as the internet, by encrypting the data transmitted between the client and the server.

    Here's how SSH works:

    1. Client-Server Connection: The client initiates a connection to the server using SSH. The client can be a computer, smartphone, or any device with SSH client software installed. The server is a remote computer that has SSH server software running.
    2. Encryption: Once the connection is established, SSH negotiates encryption algorithms with the server. This ensures that all data transmitted between the client and server is encrypted, making it difficult for anyone to intercept or decipher the information.
    3. Authentication: SSH uses various authentication methods to verify the identity of the client connecting to the server. This can include password-based authentication, public key authentication, or other authentication mechanisms.
    4. Secure Communication: Once the client is authenticated, SSH creates a secure channel between the client and server. This channel is used for all subsequent communication, including commands, file transfers, and other data exchange.
    5. Command Execution: The client can now send commands to the server securely. The server executes these commands and sends the output back to the client over the encrypted channel.
    6. File Transfer: SSH also supports secure file transfer between the client and server. This allows files to be securely uploaded or downloaded from the server.

    Overall, SSH ensures secure remote access and communication by encrypting data, authenticating users, and establishing a secure channel for communication between the client and server. It is widely used in various scenarios, such as remote server administration, secure file transfers, and tunneling network connections.

  • Why is SSH important for secure remote access to network devices?

    SSH (Secure Shell) is important for secure remote access to network devices for several reasons:

    1. Encryption: SSH provides strong encryption for data transmission, ensuring that information sent between the client and the server is protected from eavesdropping or interception. This prevents unauthorized access to sensitive data and ensures the confidentiality of the communication.
    2. Authentication: SSH uses various authentication methods, such as passwords, public key cryptography, or two-factor authentication, to verify the identity of the user or client device. This ensures that only authorized individuals can access the network devices remotely, reducing the risk of unauthorized access and potential security breaches.
    3. Integrity: SSH also ensures the integrity of the data being transmitted. It uses cryptographic mechanisms to detect any tampering or modification of data during transit. If any changes are detected, the connection is terminated, preventing the transmission of compromised or altered data.
    4. Portability: SSH is widely supported across different operating systems and platforms, making it a versatile and accessible solution for remote access. It allows network administrators to securely manage network devices from various locations and devices, including desktops, laptops, or mobile devices.
    5. Secure File Transfer: In addition to remote access, SSH also provides secure file transfer capabilities through tools like SCP (Secure Copy) and SFTP (Secure File Transfer Protocol). This allows administrators to securely transfer files between their local machines and network devices without the need for additional, potentially less secure, protocols.

    Overall, SSH plays a crucial role in ensuring the security and privacy of remote access to network devices, protecting sensitive data, and preventing unauthorized access or tampering.
