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 Idis also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

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

Although NAS DR-2104P can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

Where are user’s files stored?

The Idis DR-2104P network-attached storage keeps OS Linux operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.

  • 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.
