How to recover data from Huawei OceanStor 2200 V3 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 Huawei OceanStor 2200 V3

Huawei OceanStor 2200 V3 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from OceanStor 2200 V3.

How to recover data from NAS Huawei OceanStor 2200 V3

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 Huawei also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can file system corruption impact data integrity on NAS Huawei OceanStor 2200 V3 devices?

File system corruption on NAS Huawei OceanStor 2200 V3 devices can have a significant impact on data integrity. Here are a few ways it can affect the device:

  1. Data Loss: File system corruption can lead to the loss of data stored on the NAS device. It can make files and directories inaccessible or completely disappear from the file system.
  2. Data Inconsistency: Corruption can result in inconsistencies within the file system, causing data to become incorrect or invalid. This can lead to data errors, such as incorrect values or missing information within files.
  3. Data Access Issues: Corrupted file systems may cause difficulties in accessing data stored on the NAS device. Users may experience slow read/write speeds, frequent crashes, or even complete system unresponsiveness.
  4. Data Recovery Challenges: Recovering data from a corrupted file system can be challenging and may require specialized tools or professional assistance. In some cases, data recovery may not be possible at all, resulting in permanent data loss.
  5. System Instability: File system corruption can destabilize the overall functioning of the NAS device. It may lead to system crashes, unexpected reboots, or other performance issues, impacting the reliability and availability of stored data.

To mitigate these risks and ensure data integrity, it's essential to regularly back up data on the NAS device, implement proper data protection mechanisms such as RAID, and regularly monitor the health of the file system to detect and repair any corruption issues promptly.

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

Although NAS OceanStor 2200 V3 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 Huawei OceanStor 2200 V3. 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.

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 Huawei OceanStor 2200 V3 network-attached storage keeps OS Linux 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 Huawei OceanStor 2200 V3 device be done if the storage disks have been accidentally overwritten or reformatted?

      Data recovery from a NAS (Network Attached Storage) device like the Huawei OceanStor 2200 V3 can be challenging if the storage disks have been overwritten or reformatted. When data is overwritten or reformatted, the original data is typically erased or replaced, making it difficult to recover.

      However, data recovery may still be possible in certain cases. It depends on several factors, such as the extent of the overwriting or reformatting, the specific file system used on the NAS, and the actions taken after the data loss.

      If the data has been recently overwritten or reformatted, it may be worth contacting a professional data recovery service as soon as possible. They may have specialized tools and techniques to attempt recovery, although success cannot be guaranteed.

      It is important to note that attempting data recovery on your own or using unreliable software can potentially worsen the situation and make recovery more difficult or even impossible.
