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

Are there any specific network security measures to implement for safeguarding NAS Idis DR-2216P devices against data loss?

Yes, there are several network security measures that can be implemented to safeguard NAS Idis DR-2216P devices against data loss. Here are some recommendations:

  1. Secure Network Configuration: Ensure that the NAS device is connected to a secure network. Use strong passwords for network access and disable any unnecessary services or ports.
  2. Firewall Protection: Implement a firewall to restrict unauthorized access to the NAS device. Configure the firewall to only allow necessary network traffic and block all other incoming connections.
  3. Regular Firmware Updates: Keep the NAS device's firmware up to date with the latest security patches. Manufacturers often release firmware updates to address vulnerabilities and improve security.
  4. Enable Authentication and Access Controls: Implement strong authentication mechanisms such as two-factor authentication (2FA) to prevent unauthorized access. Also, configure access controls to restrict user privileges and limit access to sensitive data.
  5. Data Encryption: Enable encryption for data stored on the NAS device. This ensures that even if the device is compromised, the data remains protected and unreadable.
  6. Backup and Disaster Recovery: Implement a regular backup strategy to create copies of the data stored on the NAS device. Store backups in a separate location or on a different device to protect against data loss in case of device failure or physical damage.
  7. Network Intrusion Detection System (NIDS): Deploy a NIDS to monitor network traffic and detect any suspicious activities or intrusion attempts. This helps in identifying and mitigating potential security threats.
  8. Physical Security: Ensure that the NAS device is physically secured in a locked room or cabinet to prevent unauthorized access or theft.
  9. User Education: Educate users about best practices for network security, such as avoiding suspicious links or attachments, using strong passwords, and regularly updating software.

By implementing these network security measures, you can significantly reduce the risk of data loss and enhance the overall security of your NAS Idis DR-2216P devices.
