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.

Can the use of redundant power supplies reduce the chances of data loss on NAS Idis DR-6308P-SA devices?

Yes, the use of redundant power supplies can reduce the chances of data loss on NAS Idis DR-6308P-SA devices. Redundant power supplies provide a backup power source in case one power supply fails, ensuring uninterrupted power supply to the device. This can help prevent sudden power outages or fluctuations that could lead to data loss or corruption. By having redundant power supplies, the NAS device remains operational even if one power supply fails, reducing the risk of data loss.

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

Although NAS DR-6308P-SA 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Idis DR-6308P-SA. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

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-6308P-SA 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.

      There are no specific hardware requirements for data recovery from an Idis DR-6308P-SA NAS device. However, you will need a computer or laptop with network connectivity to access the NAS device and recover the data. Additionally, you may need data recovery software or services depending on the specific situation and the condition of the NAS device.

  • Are there any specific security measures or encryption protocols implemented in the NAS Idis DR-6308P-SA to ensure secure network communication?

    According to the available information, the NAS Idis DR-6308P-SA is a network video recorder (NVR) rather than a network-attached storage (NAS) device. However, it is important to note that specific security measures and encryption protocols can vary depending on the firmware version and configuration of the device.

    That being said, Idis, the manufacturer of the DR-6308P-SA, typically implements several security measures in their NVRs. Some of these measures may include:

    1. User Authentication: The NVR may require users to authenticate themselves with a username and password before accessing the system.
    2. Secure Communication: The NVR may support encrypted communication protocols such as HTTPS (HTTP over SSL/TLS) to ensure secure data transmission between the device and clients.
    3. User Access Control: The NVR may provide granular user access control, allowing administrators to define different user roles and permissions to restrict access to specific functionalities or video streams.
    4. Network Security: The NVR may support network security features like IP filtering, which allows administrators to restrict access to the device based on IP addresses or ranges.
    5. Firmware Updates: Regular firmware updates are crucial to address security vulnerabilities and improve the overall security of the NVR. It is recommended to keep the firmware up to date to benefit from the latest security enhancements.

    It is always advisable to consult the product documentation, user manual, or contact the manufacturer directly for the most accurate and up-to-date information regarding the security measures and encryption protocols implemented in a specific device model.
