How to Recover Deleted Data from NAS Lenovo ThinkSystem SR860 Mission-Critical Server: A Step-by-Step Guide

Recover data from damaged RAID arrays inaccessible from a computer.

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 Lenovo 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 Lenovo ThinkSystem SR860 Mission-Critical Server devices against data loss?

Yes, there are several network security measures that can be implemented to safeguard NAS Lenovo ThinkSystem SR860 Mission-Critical Server devices against data loss. Here are some key measures:

  1. Access Control: Implement strict access control policies to ensure only authorized personnel have access to the server. Use strong passwords and enforce regular password changes. Consider implementing multi-factor authentication for added security.
  2. Firewall: Configure and maintain a firewall to control incoming and outgoing network traffic. This helps prevent unauthorized access and protects against potential attacks.
  3. Encryption: Enable encryption for data in transit and at rest. This ensures that even if the data is intercepted or stolen, it remains unreadable without the encryption key.
  4. Regular Updates and Patching: Keep the server's operating system, applications, and firmware up to date with the latest security patches. Regularly check for updates and apply them promptly to protect against known vulnerabilities.
  5. Intrusion Detection/Prevention System (IDS/IPS): Deploy an IDS/IPS solution to monitor network traffic and detect any suspicious activity or potential attacks. This helps in identifying and mitigating threats in real-time.
  6. Backup and Disaster Recovery: Implement a robust backup strategy to regularly back up critical data stored on the NAS server. Store backups in a separate location to protect against data loss due to hardware failure, natural disasters, or cyber-attacks.
  7. Network Segmentation: Segment the network to isolate the NAS server from other systems and devices. This limits the potential attack surface and prevents lateral movement of threats within the network.
  8. Logging and Monitoring: Enable logging and monitoring on the NAS server to track and analyze any unusual activities or security incidents. Implement a centralized logging solution to consolidate logs from multiple devices for easier analysis.
  9. Antivirus/Antimalware: Install and regularly update antivirus and antimalware software on the NAS server to detect and remove any malicious software that may compromise data integrity.
  10. User Education and Awareness: Train users on best practices for data security, such as avoiding suspicious emails, not clicking on unknown links, and recognizing social engineering attempts. Regularly educate users about the importance of data protection and the potential risks associated with mishandling sensitive information.

It is important to note that these measures should be implemented as part of a comprehensive security strategy, tailored to the specific needs and requirements of your organization.
