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 Synology 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 Synology ioSafe 1515+ devices?

Regular performance monitoring and optimization can help in preventing data loss on NAS Synology ioSafe 1515+ devices in the following ways:

Early detection of issues: Regular monitoring allows you to identify any performance issues or anomalies that may indicate potential problems with the device. By detecting these issues early on, you can take proactive steps to address them before they lead to data loss.
Maintaining optimal performance: Monitoring the performance of your NAS device helps ensure that it is operating at its peak efficiency. By optimizing settings, storage configurations, and network performance, you can reduce the risk of data loss due to system slowdowns, bottlenecks, or failures.
Monitoring storage health: Regularly monitoring the health of your storage drives is crucial for preventing data loss. By monitoring metrics such as SMART (Self-Monitoring, Analysis, and Reporting Technology) data, you can identify signs of drive degradation or potential failures. This allows you to replace failing drives before they lead to data loss.
RAID monitoring: If you have configured your ioSafe 1515+ device with RAID (Redundant Array of Independent Disks), monitoring the RAID array is essential. Regularly checking the status of the RAID array, including the integrity of the data and the synchronization of drives, helps identify any potential issues that could result in data loss.
Backup monitoring: It is important to monitor the status and effectiveness of your backup processes. Regularly verify that backups are running successfully, and periodically test the restoration process to ensure that your data can be recovered in case of a failure.
Firmware and software updates: Keeping your NAS device's firmware and software up to date is crucial for security and performance reasons. Regularly monitoring for updates and applying them in a timely manner helps ensure that your device is protected against known vulnerabilities and that it operates optimally.

By regularly monitoring and optimizing the performance of your NAS Synology ioSafe 1515+ device, you can minimize the risk of data loss and ensure the safety and integrity of your data.

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