How to recover data from Qsan XCubeSAN XS3216 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 XCubeSAN XS3216

Qsan XCubeSAN XS3216 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from XCubeSAN XS3216.

How to recover data from NAS Qsan XCubeSAN XS3216

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 preventive measures to minimize the risk of data loss on NAS Qsan XCubeSAN XS3216 devices?

Yes, there are several preventive measures that can be taken to minimize the risk of data loss on NAS Qsan XCubeSAN XS3216 devices:

  1. Regular backups: Implement a regular backup strategy to ensure that important data is regularly backed up to an external storage device or cloud storage. This will help in recovering the data in case of any data loss or system failure.
  2. RAID configuration: Configure the XS3216 device with a RAID (Redundant Array of Independent Disks) level that suits your needs. RAID levels like RAID 1, RAID 5, or RAID 6 provide redundancy and can help protect against data loss in case of a disk failure.
  3. UPS (Uninterruptible Power Supply): Connect the XS3216 device to a UPS to protect it from sudden power outages or fluctuations. This will help prevent data corruption or loss due to sudden power failures.
  4. Firmware updates: Keep the firmware of the XS3216 device up to date. Regularly check for firmware updates provided by Qsan and apply them to ensure that the device has the latest bug fixes and security patches.
  5. Security measures: Implement proper security measures like strong passwords, firewall settings, and access controls to prevent unauthorized access to the XS3216 device. This will help protect your data from potential security breaches.
  6. Regular monitoring: Monitor the XS3216 device regularly to identify any potential issues or errors. This can be done through the device's management interface or by using monitoring software. Promptly address any identified issues to prevent data loss.
  7. Disaster recovery plan: Develop a comprehensive disaster recovery plan that includes steps to be taken in case of data loss or system failure. This plan should outline the procedures for data recovery, including the use of backups and any necessary hardware replacements.

By following these preventive measures, you can minimize the risk of data loss on NAS Qsan XCubeSAN XS3216 devices and ensure the safety of your data.

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

Although NAS XCubeSAN XS3216 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 Qsan XCubeSAN XS3216. 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.

XCubeSAN XS3216 has 16 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • RAID 5;
  • RAID 6;
  • RAID 50;
  • RAID 60;
  • JBOD;

NAS supports:

  • 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 Qsan XCubeSAN XS3216 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 data recovery from a NAS Qsan XCubeSAN XS3216 device be performed if there are issues with the network router or switch?
    • Hetman Software
      Hetman Software 5.09.2023 17:00 #

      Yes, data recovery from a NAS Qsan XCubeSAN XS3216 device can still be performed even if there are issues with the network router or switch. The network router or switch is responsible for connecting the NAS device to the network, but it does not affect the data stored on the NAS itself.

      If there are issues with the network router or switch, it may result in the NAS device being temporarily inaccessible from the network. However, the data stored on the NAS drives should still be intact and recoverable.

      To perform data recovery in such a scenario, you would need to directly connect to the NAS device using a computer or another device. This can be done by connecting the NAS directly to the computer using an Ethernet cable or by accessing the NAS through its management interface if it has one.

      Once connected, you can then use data recovery software or services to scan and recover the data from the NAS drives. It's important to note that data recovery can be a complex process, and it's recommended to consult with a professional data recovery service if you're not familiar with the process or if the data is critical.
