How to recover data from Qsan XCubeSAN XS3316 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 XS3316

Qsan XCubeSAN XS3316 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 XS3316.

How to recover data from NAS Qsan XCubeSAN XS3316

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 XS3316 devices?

Yes, there are several preventive measures you can take to minimize the risk of data loss on NAS Qsan XCubeSAN XS3316 devices:

  1. Regular backups: Implement a regular backup strategy to ensure that your data is regularly backed up to a separate storage device or cloud storage. This will help you recover your data in case of any data loss event.
  2. RAID configuration: Configure your Qsan XCubeSAN XS3316 device with a RAID (Redundant Array of Independent Disks) configuration. RAID provides data redundancy by distributing data across multiple disks, which helps protect against disk failures and minimize the risk of data loss.
  3. UPS (Uninterruptible Power Supply): Connect your Qsan XCubeSAN XS3316 device to a UPS to protect it against power outages and fluctuations. Sudden power loss can lead to data corruption or loss, and a UPS will provide temporary power during such events, allowing you to properly shut down the device.
  4. Regular firmware updates: Keep your Qsan XCubeSAN XS3316 device's firmware up to date. Firmware updates often include bug fixes and security patches that can help prevent data loss due to software vulnerabilities.
  5. Implement access controls: Set up proper access controls and user permissions to restrict unauthorized access to your Qsan XCubeSAN XS3316 device. This will help prevent accidental or intentional data deletion or modification.
  6. Implement encryption: Enable encryption on your Qsan XCubeSAN XS3316 device to protect your data from unauthorized access. Encryption ensures that even if someone gains physical access to the drives, they won't be able to access the data without the encryption key.
  7. Monitor system health: Regularly monitor the health and performance of your Qsan XCubeSAN XS3316 device. Use the built-in monitoring tools or third-party software to keep an eye on disk health, temperature, and other critical parameters. This will help you identify and address any potential issues before they lead to data loss.

By following these preventive measures, you can minimize the risk of data loss on your Qsan XCubeSAN XS3316 devices and ensure the safety and availability of your data.

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

Although NAS XCubeSAN XS3316 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 XCubeSAN XS3316 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.

    To stream and playback media files stored on the XS3316, you would need to connect it to a media player or server that supports the desired formats and resolutions. The XS3316 can provide the necessary storage capacity and performance for smooth streaming and playback, but the actual playback capabilities would be determined by the software or hardware used for streaming and playback.

  • Are there any limitations or considerations to keep in mind when using the NAS Qsan XCubeSAN XS3316 as a media center, such as storage capacity, connectivity options, or compatibility with popular media center software?

    When using the NAS Qsan XCubeSAN XS3316 as a media center, there are a few limitations and considerations to keep in mind:

    1. Storage Capacity: The XS3316 offers a maximum raw capacity of 384TB, but the usable capacity will be lower due to RAID configuration and system overhead. Depending on your media collection size and growth plans, you may need to consider additional storage expansion options.
    2. Connectivity Options: The XS3316 supports various connectivity options like Ethernet, Fibre Channel, and iSCSI. However, it's important to ensure that your media center devices (such as TVs, streaming devices, etc.) are compatible with the available connectivity options provided by the NAS.
    3. Compatibility with Media Center Software: The XS3316 is compatible with popular media center software like Plex, Kodi, Emby, etc. However, it's essential to check the system requirements and compatibility of the specific media center software you plan to use. Ensure that the NAS meets the software's minimum requirements and that the software supports the XS3316's operating system.
    4. Processing Power: The XS3316 is a NAS device primarily designed for storage purposes. While it can handle basic media streaming and file serving, it may not have the same processing power as dedicated media center devices. If you plan to run resource-intensive media center applications or require transcoding capabilities, you might need to consider additional hardware or a dedicated media center device.
    5. User Interface: The XS3316 may not offer a user-friendly interface specifically designed for media center purposes. You might need to rely on the web-based management interface provided by the NAS or use a separate device (like a computer or smartphone) to control and manage your media center activities.

    Overall, the XS3316 can serve as a media center, but it's important to consider its storage capacity, connectivity options, compatibility with media center software, processing power, and user interface to ensure it meets your specific media center requirements.
