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 QNAP 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 precautions to take while migrating data between NAS QNAP Turbo Station TS-439U-RP / SP devices?

Yes, there are specific precautions to take while migrating data between NAS QNAP Turbo Station TS-439U-RP/SP devices. Here are some important steps to follow:

  1. Backup your data: Before starting the migration process, it is crucial to create a backup of all your important data. This ensures that even if something goes wrong during the migration, your data will remain safe.
  2. Check compatibility: Make sure that the target NAS device (TS-439U-RP/SP) is compatible with the source NAS device. Check the QNAP website or user manual for compatibility information.
  3. Update firmware: Ensure that both the source and target NAS devices are running the latest firmware version. Updating the firmware reduces the risk of compatibility issues and ensures a smoother migration process.
  4. Verify network connectivity: Ensure that both NAS devices are connected to the same network and can communicate with each other. Check the network settings and configurations to avoid any connectivity issues.
  5. Plan the migration: Decide on the migration method you want to use. QNAP provides various migration options such as QNAP External RAID Manager, QNAP NetBak Replicator, or QNAP Snapshot Replica. Choose the method that suits your requirements and follow the provided instructions.
  6. Follow the migration process: Depending on the chosen migration method, follow the step-by-step instructions provided by QNAP. Pay attention to any warnings or precautions mentioned in the documentation.
  7. Monitor the migration process: During the migration, keep an eye on the progress and make sure there are no errors or issues. If you encounter any problems, refer to the QNAP support resources or contact their technical support for assistance.
  8. Test the migrated data: Once the migration is complete, verify that all your data has been successfully migrated to the new NAS device. Access your files, folders, and applications to ensure everything is working as expected.

By following these precautions, you can minimize the risk of data loss or migration issues while transferring data between NAS QNAP Turbo Station TS-439U-RP/SP devices.
