How to recover data from NAS Qsan XCubeNAS XN7012R

Qsan XCubeNAS XN7012R 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 XN7012R.

How to recover data from NAS Qsan XCubeNAS XN7012R

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.

Are there any recommended practices for off-site backup storage to prevent complete data loss in the event of a disaster?

Yes, there are several recommended practices for off-site backup storage to prevent complete data loss in the event of a disaster. Here are some key practices:

  1. Choose a geographically distant location: Select an off-site storage location that is located far away from your primary site. This helps to ensure that both locations are not affected by the same disaster.
  2. Use a secure and reliable facility: Ensure that the off-site storage facility provides adequate security measures, such as controlled access, surveillance systems, and fire suppression systems. It should also have a reliable power supply and backup systems to avoid any interruptions.
  3. Regularly backup your data: Implement a regular backup schedule to ensure that your data is backed up frequently. This can be done daily, weekly, or depending on the criticality of your data. Automated backup solutions can simplify this process.
  4. Encrypt your data: Encrypt the data before sending it to the off-site storage facility. This adds an extra layer of security and ensures that even if it falls into the wrong hands, it remains unreadable.
  5. Test the backup and recovery process: Regularly test the backup and recovery process to ensure that the data can be successfully restored. This helps identify any issues or gaps in the backup strategy and allows for necessary adjustments.
  6. Use multiple backup locations: Consider using multiple off-site backup locations to further minimize the risk of data loss. This can include cloud storage providers, multiple data centers, or a combination of both.
  7. Maintain documentation and inventory: Keep a detailed inventory of the data stored off-site and maintain documentation of the backup and recovery procedures. This will help in quickly identifying and retrieving the required data in case of a disaster.
  8. Implement a disaster recovery plan: Develop a comprehensive disaster recovery plan that outlines the steps to be taken in the event of a disaster. This plan should include the process for retrieving data from the off-site storage facility and restoring it to the primary site.

By following these recommended practices, you can significantly reduce the risk of complete data loss and ensure business continuity in the face of a disaster.

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

Although NAS XCubeNAS XN7012R 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 XN7012R 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.

    Is it possible to recover data from a NAS Qsan XCubeNAS XN7012R device that has undergone a system restore or factory reset?
    • Hetman Software

      It is generally not possible to recover data from a NAS device that has undergone a system restore or factory reset. When a system restore or factory reset is performed, all data and settings on the device are typically erased and restored to their original state. This process often includes formatting the storage drives, which permanently deletes all data stored on them.

      If you have important data on the NAS device that you need to recover, it is recommended to immediately stop using the device and contact a professional data recovery service. They may be able to perform specialized techniques to recover data from the storage drives, even after a system restore or factory reset. However, the success of data recovery depends on various factors, including the extent of the reset and any subsequent data overwriting that may have occurred.
