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 Thecus 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 known issues or limitations when using NAS Thecus N8800+ devices with virtualization platforms such as VMware or Hyper-V?

There are a few known issues and limitations when using Thecus N8800+ devices with virtualization platforms like VMware or Hyper-V. Some of them include:

  1. Limited hardware support: The N8800+ may not be compatible with all the hardware components required for virtualization platforms. For example, it may not support certain network adapters or storage controllers that are commonly used in virtualized environments.
  2. Performance limitations: The N8800+ may not provide the same level of performance as dedicated storage devices designed for virtualization. It may not be able to handle high I/O workloads or provide sufficient throughput for demanding virtualized applications.
  3. Lack of advanced features: The N8800+ may lack some advanced features that are commonly found in dedicated storage devices for virtualization. For example, it may not support features like thin provisioning, deduplication, or live migration.
  4. Limited scalability: The N8800+ may have limitations in terms of scalability, such as the number of virtual machines or virtual disks it can support. It may not be suitable for large-scale virtualized environments with a high number of VMs or storage requirements.
  5. Limited integration and management capabilities: The N8800+ may not provide the same level of integration and management capabilities with virtualization platforms as dedicated storage solutions. This can make it more difficult to configure, monitor, and manage the storage resources in a virtualized environment.

It is always recommended to check the compatibility and performance requirements of the specific virtualization platform and the Thecus N8800+ device before using them together in a production environment.

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

Although NAS N8800+ 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 Thecus N8800+ 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.

  • Are there any limitations or considerations to keep in mind while copying files from the NAS Thecus N8800+ to cloud services, such as file size restrictions or compatibility issues?

    When copying files from a NAS like Thecus N8800+ to cloud services, there are some limitations and considerations to keep in mind:

    1. File size restrictions: Cloud services often have limitations on the maximum file size that can be uploaded. For example, some services may have a file size limit of 2GB or 5GB. If you have large files on your NAS, you may need to split them or find a cloud service with higher file size limits.
    2. Internet connection speed: Uploading large files to the cloud can be time-consuming, especially if you have a slow internet connection. Consider the upload speed of your internet connection and the size of the files you want to transfer. It may take a significant amount of time to complete the upload.
    3. Compatibility issues: Ensure that the cloud service you choose is compatible with the file formats and types stored on your NAS. Some cloud services may have limitations on the types of files they support or may not be able to handle certain file formats. Check the compatibility requirements of the cloud service before initiating the transfer.
    4. Bandwidth limitations: Some cloud services impose bandwidth limitations, which restrict the amount of data you can transfer within a specific time period. If you have a large amount of data to transfer, you may need to consider these limitations and plan accordingly.
    5. Cost considerations: Uploading files to cloud services may incur additional costs, especially if you exceed the storage limits provided by the service or require higher upload speeds. Evaluate the pricing plans and storage options offered by the cloud service to ensure they align with your requirements and budget.
    6. Security and privacy: When transferring files to the cloud, it's crucial to consider the security and privacy aspects. Ensure that the cloud service you choose offers adequate encryption and data protection measures to safeguard your files during transit and while stored in the cloud.

    It's advisable to thoroughly research and understand the limitations and requirements of both your NAS and the cloud service before initiating the file transfer to ensure a smooth and successful process.
