Infortrend EonStor DS 2024B NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from EonStor DS 2024B.

How to recover data from NAS Infortrend EonStor DS 2024B

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 Infortrend 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 recommended practices for off-site backup storage to prevent complete data loss in the event of a disaster?

Yes, there are several recommended practices for off-site backup storage to prevent complete data loss in the event of a disaster. Here are some key recommendations:

  1. Choose a geographically distant location: Ensure that your off-site backup storage is located in a different geographical area to minimize the risk of being affected by the same disaster that impacts your primary location. This helps protect against regional disasters like earthquakes, floods, or hurricanes.
  2. Use a secure and reliable backup service: Select a reputable backup service provider that offers strong security measures, encryption, and reliable infrastructure. Look for providers with a proven track record, good customer reviews, and certifications like ISO 27001.
  3. Regularly backup your data: Implement a regular backup schedule to ensure that your data is consistently backed up and up to date. Automate the backup process whenever possible to avoid human errors or forgetfulness.
  4. Implement redundancy: Consider having multiple backup locations or providers to add an extra layer of redundancy. This ensures that even if one backup fails, you still have another copy of your data stored securely.
  5. Test your backups: Regularly test the restoration process from your off-site backup to ensure that your data can be successfully recovered. This helps identify any issues or errors in the backup process and ensures the integrity of your data.
  6. Encrypt your data: Encrypt your data before sending it to off-site backup storage. This adds an extra layer of security and ensures that even if the data is compromised, it cannot be accessed without the encryption key.
  7. Document your backup and recovery procedures: Maintain proper documentation of your backup and recovery procedures, including step-by-step instructions. This helps ensure that the process can be easily followed by anyone in your organization, even during stressful situations.
  8. Monitor and review backup logs: Regularly monitor and review backup logs to ensure that backups are completing successfully and to identify any potential issues or errors. This proactive approach helps address any problems before they result in data loss.
  9. Consider a hybrid approach: In addition to off-site backups, consider implementing a hybrid backup approach that includes local backups as well. This allows for faster data recovery in case of minor incidents or data loss scenarios that don't require full off-site restoration.

By following these recommended practices, you can significantly reduce the risk of complete data loss and ensure that your data is protected even in the event of a disaster.

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

Although NAS EonStor DS 2024B can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:
