How to recover data from Qsan XCubeNAS XN8012R NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

How to recover data from NAS Qsan XCubeNAS XN8012R

Qsan XCubeNAS XN8012R NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from XCubeNAS XN8012R.

How to recover data from NAS Qsan XCubeNAS XN8012R

Recover data from damaged RAID arrays inaccessible from a computer.

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 Qsan 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 encryption safeguard data stored on NAS Qsan XCubeNAS XN8012R devices?

Yes, encryption can safeguard data stored on NAS Qsan XCubeNAS XN8012R devices. The Qsan XCubeNAS XN8012R supports various encryption methods such as AES-256 encryption for data-at-rest protection. This means that the data stored on the device is encrypted and can only be accessed with the correct encryption key or password. This helps to ensure that even if the device is stolen or accessed by unauthorized individuals, the data remains secure and cannot be easily accessed or read.

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

Although NAS XCubeNAS XN8012R 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 Qsan XCubeNAS XN8012R network-attached storage keeps SANOS 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 the encryption options available on the Qsan XCubeNAS XN8012R and how they contribute to data security?

    The Qsan XCubeNAS XN8012R offers several encryption options to enhance data security. These options include:

    1. AES 256-bit Volume-based Encryption: This encryption method uses the Advanced Encryption Standard (AES) algorithm with a key size of 256 bits. It encrypts the entire volume, including all files and folders stored within it. This encryption ensures that even if someone gains unauthorized access to the physical drives, they won't be able to access the data without the encryption key.
    2. AES 256-bit Folder-based Encryption: Similar to volume-based encryption, this option allows you to encrypt specific folders rather than the entire volume. It provides granular control over which folders are encrypted, allowing you to encrypt only the most sensitive data. This ensures that even if someone gains access to the NAS system, they won't be able to access the encrypted folders without the encryption key.
    3. AES 256-bit Network-based Encryption: This encryption option secures the transmission of data between the XCubeNAS and other devices over the network. It encrypts the data packets using the AES 256-bit algorithm before sending them over the network, making it extremely difficult for anyone to intercept and decipher the data.

    By utilizing these encryption options, the Qsan XCubeNAS XN8012R significantly contributes to data security. The AES 256-bit encryption algorithm is widely regarded as highly secure and is used by many organizations and governments worldwide. It ensures that even if the physical drives or the NAS system itself is compromised, the encrypted data remains protected. Additionally, the network-based encryption ensures that data transmitted over the network is secure and cannot be intercepted by unauthorized individuals. Overall, these encryption options provide robust data security measures to protect sensitive information stored on the XCubeNAS XN8012R.
