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 Idis 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.

Are there any known limitations or performance bottlenecks that can increase data loss risks for NAS Idis DR-2104P devices?

There are several potential limitations and performance bottlenecks that can increase data loss risks for NAS Idis DR-2104P devices:

  1. Hardware limitations: The DR-2104P device may have certain hardware limitations, such as limited storage capacity or processing power. If the device runs out of storage space or becomes overwhelmed with data, it can lead to data loss.
  2. Network limitations: NAS devices rely on network connectivity to transfer and access data. If the network infrastructure is not robust or experiences frequent downtime, it can increase the risk of data loss. Additionally, slow network speeds can hinder data transfer and potentially increase the chances of data loss.
  3. RAID configuration: The DR-2104P device may use a RAID (Redundant Array of Independent Disks) configuration to provide data redundancy and protect against data loss. However, if the RAID configuration is not properly set up or maintained, it can become a performance bottleneck and increase the risk of data loss.
  4. Backup and recovery processes: The effectiveness of the backup and recovery processes implemented on the NAS device can impact data loss risks. If backups are not performed regularly or if the recovery processes are not reliable, it can lead to data loss in case of hardware failure or other issues.
  5. User error: Data loss can also occur due to user error, such as accidental deletion or overwriting of files. While this may not be specific to the DR-2104P device, it is still a risk that can lead to data loss.

To mitigate these risks and minimize data loss, it is important to regularly monitor the device's storage capacity, ensure a robust and reliable network infrastructure, properly configure and maintain the RAID setup, implement effective backup and recovery processes, and educate users on best practices to avoid user errors.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS DR-2104P can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

  1. Power off the NAS and disconnect it from the power source.

    WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

  2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

  3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

  4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

      Data recovery from a NAS (Network Attached Storage) device like the Idis DR-2104P can be challenging if there are issues with the operating system or firmware. In such cases, the data recovery process may become more complex and require specialized expertise.

      Here are a few points to consider:

      1. Determine the cause of the issue: It is important to identify whether the problem lies with the operating system, firmware, hardware, or any other component. This will help in understanding the extent of the issue and the potential impact on data recovery.
      2. Contact the manufacturer or technical support: Reach out to the manufacturer or technical support of the NAS device to seek guidance. They may provide troubleshooting steps or recommend specific data recovery procedures for their device.
      3. Engage professional data recovery services: If the manufacturer or technical support is unable to assist or if the issue is beyond their scope, you may need to engage professional data recovery services. These companies specialize in recovering data from various storage devices, including NAS devices. They have the necessary tools, expertise, and experience to deal with complex data recovery scenarios.
      4. Evaluate the cost and risks: Professional data recovery services can be costly, and there is always a risk that not all data can be recovered. Before proceeding, assess the importance of the data and weigh it against the potential cost and risks involved in the recovery process.

      Remember, it is crucial to have a backup strategy in place to prevent data loss. Regularly backing up your data to an external source or cloud storage can help mitigate the impact of any unforeseen issues with your NAS device.

  • Can you explain how the NAS Idis DR-2104P ensures data security and backup for photos stored centrally?

    The NAS Idis DR-2104P is a network-attached storage device designed to ensure data security and backup for photos stored centrally. Here's how it achieves these objectives:

    1. Redundant Storage: The DR-2104P typically comes with multiple hard drive bays, allowing you to configure it with RAID (Redundant Array of Independent Disks) technology. RAID can provide data redundancy by mirroring or striping data across multiple drives, ensuring that even if one drive fails, the data remains accessible.
    2. Data Encryption: The NAS supports various encryption protocols such as AES (Advanced Encryption Standard) to secure the stored photos. Encryption scrambles the data, making it unreadable to unauthorized users, and ensures that even if someone gains access to the physical drives, they cannot retrieve the data without the encryption key.
    3. User Access Controls: The DR-2104P offers user access controls, allowing you to define user permissions and access levels for different individuals or groups. This ensures that only authorized users can access the stored photos, preventing unauthorized access or accidental deletion.
    4. Remote Access and Backup: The NAS supports remote access, enabling you to access and manage the stored photos from anywhere using a secure connection. Additionally, it provides backup functionality, allowing you to schedule automatic backups of the stored photos to external drives, cloud storage, or other NAS devices. This ensures that even if the primary storage fails, the data can be restored from the backups.
    5. Snapshot and Versioning: The NAS may offer snapshot and versioning features, allowing you to capture point-in-time copies of the stored photos or maintain multiple versions of files. This can be useful in case of accidental modifications or deletions, as you can easily restore previous versions or recover deleted photos.
    6. Data Integrity Checks: The DR-2104P can perform periodic data integrity checks to ensure that the stored photos are not corrupted or modified. It verifies the integrity of the data against checksums or other algorithms, alerting you to any potential issues and allowing you to take corrective actions.

    Overall, the NAS Idis DR-2104P combines various security and backup features to ensure the safety and availability of centrally stored photos, protecting against data loss, unauthorized access, and other potential risks.
