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 recommended practices for regular testing and validation of data backups to prevent potential loss on NAS QNAP VS-8124U-RP Pro devices?

Yes, there are recommended practices for regular testing and validation of data backups to prevent potential loss on NAS QNAP VS-8124U-RP Pro devices. Here are some best practices:

  1. Regular Backup Schedule: Set up a regular backup schedule to ensure that your data is backed up at regular intervals. This can be done daily, weekly, or monthly, depending on your data's criticality and frequency of changes.
  2. Multiple Backup Copies: Maintain multiple backup copies of your data. This can include having both on-site and off-site backups. On-site backups can be stored on the QNAP NAS device, while off-site backups can be stored on external hard drives or cloud storage solutions.
  3. Verify Backup Integrity: Regularly verify the integrity of your backups by performing test restores. This involves restoring a small subset of data from the backup to ensure that it can be successfully recovered. This will help identify any issues with the backup process or data corruption.
  4. Test Recovery Procedures: Periodically test the recovery procedures to ensure that you can restore your data from the backups effectively. This includes testing the process of restoring data from both on-site and off-site backups.
  5. Monitor Backup Status: Regularly monitor the backup status and logs to ensure that backups are running successfully without any errors or warnings. This will help you identify any issues or failures in the backup process.
  6. Regularly Update Backup Software: Keep your backup software and firmware up to date to ensure that you have the latest features, bug fixes, and security patches. This will help prevent any vulnerabilities that could lead to data loss.
  7. Implement RAID or Redundancy: Consider implementing RAID (Redundant Array of Independent Disks) or other redundancy mechanisms to protect against disk failures. This will help ensure that your data remains accessible even if one or more disks fail.
  8. Regularly Monitor Disk Health: Monitor the health of your NAS disks regularly using the built-in SMART (Self-Monitoring, Analysis, and Reporting Technology) feature. This will help identify any potential disk failures in advance, allowing you to replace them before data loss occurs.

By following these recommended practices, you can minimize the risk of potential data loss and ensure the reliability of your backups on QNAP VS-8124U-RP Pro devices.

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

Although NAS VS-8124U-RP Pro 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:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

  • What RAID levels are supported by the QNAP VS-8124U-RP Pro NAS, and how do they affect data redundancy and performance?

    The QNAP VS-8124U-RP Pro NAS supports several RAID levels, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60.

    1. RAID 0: This level offers striping without any redundancy. It provides improved performance by distributing data across multiple drives but does not offer any data redundancy. If one drive fails, all data is lost.
    2. RAID 1: This level mirrors data across two drives, providing complete redundancy. It offers high data availability and allows for the failure of one drive without any data loss. However, it does not provide any performance improvement.
    3. RAID 5: This level uses striping with distributed parity. It requires a minimum of three drives and provides a good balance between performance and data redundancy. If one drive fails, the data can be rebuilt using the parity information on the remaining drives.
    4. RAID 6: Similar to RAID 5, RAID 6 uses striping with double distributed parity. It requires a minimum of four drives and provides higher data redundancy than RAID 5. It can withstand the failure of two drives simultaneously.
    5. RAID 10: This level combines mirroring (RAID 1) and striping (RAID 0). It requires a minimum of four drives and provides both performance improvement and data redundancy. It can sustain the failure of one drive in each mirrored pair without any data loss.
    6. RAID 50: RAID 50 combines striping (RAID 0) and distributed parity (RAID 5) across multiple RAID 5 arrays. It requires a minimum of six drives and offers a good balance between performance and data redundancy.
    7. RAID 60: RAID 60 combines striping (RAID 0) and double distributed parity (RAID 6) across multiple RAID 6 arrays. It requires a minimum of eight drives and provides higher data redundancy than RAID 50.

    The choice of RAID level depends on the desired balance between data redundancy and performance. RAID 1 and RAID 10 offer the highest data redundancy but do not provide significant performance improvement. RAID 0 provides the best performance but lacks data redundancy. RAID 5, RAID 6, RAID 50, and RAID 60 offer a balance between performance and data redundancy, with RAID 6 and RAID 60 providing higher levels of redundancy.

  • Can the QNAP VS-8124U-RP Pro NAS be configured to support multiple RAID arrays, and what advantages does this offer in terms of data organization and management?

    Yes, the QNAP VS-8124U-RP Pro NAS can be configured to support multiple RAID arrays. This feature allows you to divide your storage space into separate logical units, each with its own RAID configuration.

    The advantages of having multiple RAID arrays include:

    1. Data Organization: You can allocate different RAID levels to different arrays based on the importance and performance requirements of the data. For example, you can use a RAID 1 (mirroring) for critical data that requires high redundancy and a RAID 5 (striping with parity) for less critical data that requires a balance between performance and redundancy.
    2. Data Management: With multiple RAID arrays, you can easily manage and allocate storage space for different purposes. For instance, you can dedicate one RAID array for backups, another for video surveillance footage, and another for general file storage. This segregation makes it easier to manage and access specific types of data.
    3. Performance Optimization: By configuring different RAID levels for different arrays, you can optimize performance based on the specific needs of your applications. For example, you can use RAID 0 (striping) for arrays that require maximum performance, while using RAID 6 (striping with double parity) for arrays that need high performance with additional fault tolerance.
    4. Fault Isolation: If a hardware failure or data corruption occurs in one RAID array, it does not affect the other arrays. This isolation helps in containing the impact of failures and prevents data loss across the entire storage system.

    Overall, multiple RAID arrays provide flexibility, improved performance, better data organization, and enhanced fault tolerance, allowing you to tailor your storage environment to meet specific requirements for different types of data.
