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 XS5212

Qsan XCubeSAN XS5212 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 XS5212.

How to recover data from NAS Qsan XCubeSAN XS5212

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 the use of specific data compression or deduplication techniques impact the performance and data integrity on NAS Qsan XCubeSAN XS5212 devices?

Yes, the use of specific data compression or deduplication techniques can impact the performance and data integrity on NAS Qsan XCubeSAN XS5212 devices.

Data compression techniques aim to reduce the size of data by encoding it in a more efficient manner. This can save storage space and improve transfer speeds. However, compression can also introduce additional processing overhead, which may impact the performance of the device. The impact on performance will depend on the specific compression algorithm used and the hardware capabilities of the device.

Deduplication techniques eliminate redundant data by identifying and storing only unique data blocks. This can greatly reduce storage requirements, but it also requires additional processing power and memory to identify and track the duplicate data. The impact on performance will depend on the deduplication algorithm used and the amount of duplicate data present.

In terms of data integrity, both compression and deduplication techniques can introduce risks. Compression algorithms may have vulnerabilities that could potentially result in data corruption or loss if not implemented correctly. Deduplication can also introduce risks if the deduplication index becomes corrupted or if there are errors in the identification of duplicate data blocks.

To ensure optimal performance and data integrity, it is important to carefully evaluate and test the specific data compression or deduplication techniques used on Qsan XCubeSAN XS5212 devices. It is also recommended to have regular backups and monitoring in place to detect and address any potential issues.

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

Although NAS XCubeSAN XS5212 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 XS5212 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.

  • Are there any limitations or considerations to keep in mind when copying data from Qsan XCubeSAN XS5212 to cloud services, such as data transfer speeds or potential compatibility issues?

    When copying data from Qsan XCubeSAN XS5212 to cloud services, there are certain limitations and considerations to keep in mind:

    1. Data Transfer Speed: The data transfer speed depends on various factors such as your internet connection speed, the size of the data being transferred, and the efficiency of the cloud service provider's infrastructure. Large amounts of data may take a significant amount of time to transfer.
    2. Bandwidth Limitations: If you have limited bandwidth or a data cap on your internet connection, transferring large amounts of data to the cloud may consume a significant portion of your bandwidth or exceed your data cap. This can result in additional costs or slower internet speeds for other activities.
    3. Compatibility Issues: Ensure that the cloud service you choose supports the protocols and file systems used by Qsan XCubeSAN XS5212. It is important to check if the cloud service is compatible with the NAS device to avoid any compatibility issues during the data transfer process.
    4. Data Security: Consider the security measures provided by the cloud service provider. Ensure that your data is encrypted during transfer and at rest in the cloud to protect it from unauthorized access or breaches.
    5. Cost Considerations: Transferring data to cloud services may incur additional costs, especially if you exceed the storage limits or require additional services. Check the pricing structure of the cloud service provider to understand the potential costs involved.
    6. Network Stability: A stable and reliable network connection is crucial for successful data transfer. Unstable or intermittent network connections may result in interrupted transfers or data corruption.
    7. Data Transfer Methods: Depending on the cloud service provider, different methods for data transfer may be available, such as direct transfer over the internet, physical shipment of storage devices, or specialized data transfer appliances. Consider the available options and choose the most suitable method based on your requirements.

    It is recommended to thoroughly research and plan the data transfer process to mitigate any potential limitations or issues that may arise during the transfer from Qsan XCubeSAN XS5212 to cloud services.
