Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Digiever often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Are there any recommended practices for regular testing and validation of data backups to prevent potential loss on NAS Digiever DS-484192-RM Pro+ devices?

Yes, there are recommended practices for regular testing and validation of data backups to prevent potential loss on NAS Digiever DS-484192-RM Pro+ devices. Here are some suggestions:

  1. Regularly schedule backup tests: Set up a regular backup testing schedule to ensure that backups are functioning correctly. This can be done weekly, monthly, or based on your organization's requirements.
  2. Perform test restores: Regularly restore a subset of backed-up data to ensure that the restore process is working properly. This will help identify any issues with the backup files or the restore process itself.
  3. Verify data integrity: Use tools or software provided by Digiever to verify the integrity of the backup data. This ensures that the data has not been corrupted or modified during the backup process.
  4. Monitor backup logs: Regularly review the backup logs provided by the Digiever DS-484192-RM Pro+ device to ensure that backups are completing successfully without errors or warnings. Investigate and resolve any issues identified in the logs.
  5. Test disaster recovery procedures: In addition to regular backup testing, periodically test your disaster recovery procedures. This involves simulating a complete system failure and restoring data from backups to ensure that you can recover data in case of a disaster.
  6. Keep backups off-site: It is recommended to keep a copy of backups off-site to protect against physical damage or loss of the primary NAS device. This can be done by replicating data to another Digiever NAS device located in a different location or by using cloud storage services.
  7. Regularly update firmware and software: Keep the Digiever DS-484192-RM Pro+ device firmware and backup software up to date to ensure that you have the latest bug fixes and security patches.

Remember, it is essential to document and maintain a backup and recovery plan that includes the above practices. Regularly review and update the plan as needed to adapt to changes in your organization's infrastructure and data protection requirements.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS DS-484192-RM Pro+ can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

  1. Power off the NAS and disconnect it from the power source.

    WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

  2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

  3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

  4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.
