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.

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

Although NAS DR-6216PS 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.

DR-6216PS has 6 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • RAID 5;
  • RAID 6;
  • JBOD;

NAS supports:

  • exFAT, VFAT, FAT 12 / 16 / 32;
  • NTFS / ReFS;
  • APFS / HFS+;
  • Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
  • VMFS / HikvisionFS;

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-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.

    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.
