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.

Is there a risk of data loss if a NAS Idis DR-6216PS device is physically damaged or stolen?

Yes, there is a risk of data loss if a NAS (Network Attached Storage) device like the IDIS DR-6216PS is physically damaged or stolen. NAS devices are used to store and manage data, and if the device is damaged or stolen, the data stored on it may become inaccessible or lost.

To mitigate the risk of data loss in such situations, it is recommended to implement proper backup strategies. Regularly backing up the data stored on the NAS device to an off-site location or another storage medium can help ensure that data remains safe even if the device itself is damaged or stolen. Additionally, encrypting the data stored on the NAS device can provide an extra layer of security, making it difficult for unauthorized individuals to access the data even if they gain physical access to the device.

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

Although the NAS DR-6216PS 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.

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

  • Overwriting during the recovery process;
  • Additional data loss caused by bad sectors;
  • User errors.

To create a disk image, follow these steps:

  1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

  2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

  3. When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

Where Are the User’s Files Actually Stored?

The Idis DR-6216PS 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.

    10. User-friendly interface: The NAS offers a user-friendly interface with intuitive controls and configuration options, making it easy to set up and manage the surveillance system.

    It's important to note that while the NAS Idis DR-6216PS provides robust video surveillance features, it does not offer internet access capabilities on its own. It needs to be connected to a network that provides internet connectivity for remote access and monitoring.

  • How does the NAS Idis DR-6216PS ensure secure and reliable internet connectivity?

    The NAS Idis DR-6216PS does not directly provide internet connectivity. Instead, it is a network video recorder (NVR) that is designed to store and manage video footage from IP cameras. The NVR is connected to a local network, and the internet connectivity for the NVR is typically provided by a separate router or network infrastructure.

    To ensure secure and reliable internet connectivity for the NAS Idis DR-6216PS, the following measures can be taken:

    1. Network Security: The NVR should be connected to a secure and protected network. This can be achieved by implementing firewalls, intrusion detection systems, and secure network protocols (such as WPA2 for Wi-Fi connections).
    2. Encryption: The NVR should support encryption protocols for data transmission, such as Secure Socket Layer (SSL) or Transport Layer Security (TLS). This ensures that the video footage and other data transmitted over the internet are encrypted and protected from unauthorized access.
    3. Access Control: The NVR should have robust access control mechanisms in place. This includes strong passwords, user authentication, and role-based access control. Only authorized individuals should have access to the NVR and its settings.
    4. Firmware Updates: Regular firmware updates should be applied to the NVR to ensure that any security vulnerabilities are patched. Manufacturers often release firmware updates to address security issues and improve overall performance.
    5. Network Monitoring: Continuous monitoring of the network and the NVR is essential. This can be done using network monitoring tools that detect any unusual activity or potential security threats. Monitoring helps in identifying and addressing any network or connectivity issues promptly.

    It is important to note that while the NAS Idis DR-6216PS can be connected to the internet for remote access and management, the responsibility for ensuring secure and reliable internet connectivity lies with the network infrastructure and security measures implemented in the overall network setup.
