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.

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.
