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 Buffalo 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 system monitoring and alerting help in early detection and prevention of data loss events on NAS Buffalo Drive Station HD-CE1.0TLU2 devices?

Regular system monitoring and alerting can help in early detection and prevention of data loss events on NAS Buffalo Drive Station HD-CE1.0TLU2 devices by:

  1. Monitoring disk health: Regularly monitoring the health of the hard drives in the NAS device can help identify any potential issues or failures. This can be done by monitoring parameters such as SMART (Self-Monitoring, Analysis, and Reporting Technology) attributes, temperature, and disk usage.
  2. RAID monitoring: If the NAS device is configured with RAID (Redundant Array of Independent Disks), monitoring the RAID status is crucial. RAID monitoring can detect any disk failures, degraded arrays, or synchronization issues, allowing for timely action to prevent data loss.
  3. Network monitoring: Monitoring the network connectivity and performance of the NAS device can help identify any issues that may lead to data loss. This includes monitoring network bandwidth, latency, and packet loss.
  4. File system monitoring: Monitoring the file system on the NAS device can help detect any file system errors or corruption. Regular file system checks can ensure the integrity of the stored data and prevent data loss due to file system issues.
  5. Backup monitoring: If backups are configured on the NAS device, monitoring the backup process is essential. Regularly checking the backup logs and ensuring successful backups can provide an additional layer of protection against data loss.
  6. Alerting: Setting up alert notifications for critical events can help in early detection of potential data loss events. Alerts can be configured for disk failures, RAID degradation, network connectivity issues, file system errors, or backup failures. These alerts can be sent via email, SMS, or other notification methods, ensuring prompt action can be taken to prevent data loss.

By regularly monitoring and receiving alerts for any issues related to disk health, RAID status, network connectivity, file system integrity, and backups, administrators can proactively address potential data loss events on NAS Buffalo Drive Station HD-CE1.0TLU2 devices, minimizing the risk of data loss and ensuring data availability.

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