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

  1. Physical security: Ensure that the NAS device is physically secured in a locked room or cabinet to prevent unauthorized access or theft. Limit access to only authorized personnel.
  2. Strong passwords: Set strong and unique passwords for all user accounts on the NAS device, including the administrator account. Avoid using default or easily guessable passwords.
  3. Two-factor authentication (2FA): Enable two-factor authentication for accessing the NAS device. This adds an extra layer of security by requiring a second verification method, such as a code sent to a mobile device, in addition to the password.
  4. Regular firmware updates: Keep the NAS device's firmware up to date with the latest security patches and updates. This helps to address any known vulnerabilities and ensures that the device is protected against potential exploits.
  5. Network segregation: Separate the NAS device from the public network by placing it on a separate VLAN or subnet. This helps to isolate it from potential unauthorized access attempts.
  6. Disable unnecessary services: Disable any unnecessary network services or protocols on the NAS device to minimize the attack surface. Only enable the services that are required for your specific use case.
  7. Data encryption: Enable encryption for data stored on the NAS device. This ensures that even if the device is stolen, the data remains encrypted and inaccessible to unauthorized individuals.
  8. Regular backups: Implement a regular backup strategy to ensure that important data stored on the NAS device is regularly backed up to a separate location. This helps to mitigate the impact of data loss in case of theft or other incidents.
  9. Employee training: Educate employees about the importance of physical security and the risks associated with unauthorized access or theft. Train them on best practices for securing the NAS device and handling sensitive data.

By following these recommended practices, you can significantly enhance the security of your NAS Qsan XCubeSAN XS5326 devices and protect against physical theft or unauthorized access that may lead to data loss.

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