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 Raidon also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can the use of specific file-sharing protocols impact data loss risks on NAS Raidon InTANK iR8022 devices?

The use of specific file-sharing protocols can impact data loss risks on NAS Raidon InTANK iR8022 devices in several ways:

Security vulnerabilities: Different file-sharing protocols have varying levels of security. Some protocols may have known vulnerabilities that can be exploited by attackers to gain unauthorized access to the NAS device and potentially cause data loss.
Authentication and access control: File-sharing protocols have different methods for authentication and access control. Weak or inadequate authentication mechanisms can increase the risk of unauthorized access to the NAS device, leading to data loss.
Encryption: Some file-sharing protocols support encryption of data during transmission, while others may not. If sensitive data is being shared over an insecure or unencrypted protocol, it can be intercepted and accessed by unauthorized parties, leading to data loss.
Data integrity: Certain file-sharing protocols have built-in mechanisms to ensure data integrity during transmission. These mechanisms can detect and correct errors or corruption in the data. Using protocols without such mechanisms can increase the risk of data loss due to undetected errors or corruption.
Compatibility and interoperability: Different file-sharing protocols may have varying levels of compatibility and interoperability with different operating systems and devices. Using protocols that are not fully compatible with the NAS device or client systems can lead to data loss or corruption during file transfers.

To mitigate data loss risks, it is important to choose file-sharing protocols that prioritize security, authentication, access control, encryption, data integrity, and compatibility. Regularly updating the NAS device's firmware and applying security patches can also help minimize vulnerabilities and protect against potential data loss. Additionally, implementing proper backup strategies and disaster recovery plans can further safeguard data in case of any unforeseen events or data loss incidents.
