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 QNAP 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.

How can regular performance monitoring and optimization help in preventing data loss on NAS QNAP Turbo Station TS-432XU / TS-432XU-RP devices?

Regular performance monitoring and optimization can help in preventing data loss on NAS QNAP Turbo Station TS-432XU / TS-432XU-RP devices in the following ways:

Early detection of hardware failures: Regular monitoring of system performance metrics like CPU usage, memory usage, and disk health can help identify any potential hardware failures or issues before they cause data loss. For example, if a hard drive starts showing signs of impending failure, such as high error rates or excessive bad sectors, it can be replaced proactively to prevent data loss.
RAID monitoring and maintenance: QNAP Turbo Station devices support various RAID configurations for data redundancy and protection. Regular monitoring of RAID status and performance can help identify any issues with the RAID array, such as degraded or failed disks, and take appropriate actions like rebuilding the array or replacing faulty disks to prevent data loss.
Backup monitoring: QNAP NAS devices provide built-in backup solutions like QNAP Hybrid Backup Sync, which allows users to schedule and automate backups to external storage or cloud services. Regular monitoring of backup jobs ensures that backups are running successfully and that data is being properly backed up, reducing the risk of data loss in case of device failure or accidental deletion.
Performance optimization: Monitoring system performance metrics can help identify any performance bottlenecks or issues that could potentially lead to data loss. For example, if the NAS device is experiencing high CPU or memory usage, it may impact the overall system performance and increase the risk of data loss. Optimizing system resources, such as closing unnecessary applications or services, can help maintain optimal performance and reduce the chances of data loss.
Firmware and software updates: Regularly updating the firmware and software on the NAS device is essential for keeping it secure and up to date with the latest bug fixes and performance improvements. These updates often include patches for known vulnerabilities that could be exploited to cause data loss. Monitoring for firmware and software updates and applying them in a timely manner can help prevent data loss due to security breaches or software-related issues.

In summary, regular performance monitoring and optimization of NAS QNAP Turbo Station TS-432XU / TS-432XU-RP devices can help in early detection of hardware failures, monitoring and maintaining RAID configurations, ensuring successful backups, optimizing system performance, and staying up to date with firmware and software updates, all of which contribute to preventing data loss.
