How to recover data from Infortrend EonStor DS 4024U 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 Infortrend EonStor DS 4024U

Infortrend EonStor DS 4024U NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from EonStor DS 4024U.

How to recover data from NAS Infortrend EonStor DS 4024U

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 Infortrend 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 redundant power supplies reduce the chances of data loss on NAS Infortrend EonStor DS 4024U devices?

Yes, the use of redundant power supplies can help reduce the chances of data loss on NAS Infortrend EonStor DS 4024U devices. Redundant power supplies provide a backup power source in case one of the power supplies fails. This ensures continuous power supply to the device, reducing the risk of unexpected shutdowns or power outages that could lead to data loss or corruption. By having redundant power supplies, the NAS device can maintain its operations even if one power supply fails, enhancing the overall reliability and availability of the system.

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

Although NAS EonStor DS 4024U 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 Infortrend EonStor DS 4024U 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.

  • How does the NAS Infortrend EonStor DS 4024U handle VPN connections and what protocols does it support?

    The NAS Infortrend EonStor DS 4024U does not handle VPN connections directly. It is primarily a storage device that provides network-attached storage (NAS) capabilities. VPN connections are typically established at the network level, outside the scope of the NAS device.

    However, the NAS device can be integrated into a network environment that has a VPN infrastructure in place. In such cases, clients connecting to the NAS device can establish VPN connections using the supported protocols of the VPN infrastructure.

    The supported VPN protocols depend on the VPN infrastructure in use. Common VPN protocols include:

    1. IPsec (Internet Protocol Security): A widely used protocol for secure communication over the internet. It provides encryption and authentication for VPN connections.
    2. SSL/TLS (Secure Sockets Layer/Transport Layer Security): Often used for secure remote access to web applications. SSL/TLS VPNs are typically browser-based and provide secure access to resources through a web portal.
    3. PPTP (Point-to-Point Tunneling Protocol): An older VPN protocol that provides basic encryption and authentication. It is less secure compared to IPsec and SSL/TLS.
    4. L2TP (Layer 2 Tunneling Protocol): Often used in combination with IPsec to provide more secure VPN connections. L2TP itself does not provide encryption or authentication but is commonly used as a tunneling protocol.

    It is essential to consult the documentation of your specific VPN infrastructure to determine the supported protocols and configuration options for establishing VPN connections with the NAS device.

  • Can the NAS Infortrend EonStor DS 4024U be easily configured and managed as a VPN server, and what level of security does it provide for VPN connections?

    The NAS Infortrend EonStor DS 4024U is primarily designed as a storage device and may not have built-in VPN server functionality. It is recommended to check the official documentation or contact Infortrend support to confirm if this specific model supports VPN server configuration.

    If the NAS does support VPN server functionality, its level of security will depend on the available VPN protocols and encryption options. Common VPN protocols such as OpenVPN, IPSec, or L2TP/IPSec provide varying levels of security. OpenVPN is generally considered to be highly secure, while IPSec offers strong encryption as well. L2TP/IPSec is a widely supported protocol but may have some security concerns.

    To ensure the security of VPN connections, it is essential to keep the NAS firmware up to date, use strong encryption algorithms, enforce secure password policies, and follow best practices for network security. It is also recommended to consult with a network security professional to evaluate the specific security features and capabilities of the NAS device.
