How to recover data from Uniview VX1824-V2 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 Uniview VX1824-V2

Uniview VX1824-V2 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from VX1824-V2.

How to recover data from NAS Uniview VX1824-V2

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 Uniview 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 frequently should data be backed up to prevent loss on NAS Uniview VX1824-V2 devices?

To prevent data loss on NAS Uniview VX1824-V2 devices, it is recommended to back up the data regularly. The frequency of backup depends on the importance of the data and the rate at which it is being updated or modified.

For critical data that is frequently changing, a daily backup is typically recommended. This ensures that any recent changes or updates are captured and can be easily restored if needed.

For less critical data or data that doesn't change frequently, a weekly or monthly backup may be sufficient. However, it is always best to err on the side of caution and backup more frequently if possible.

Additionally, it is important to consider the storage capacity of the NAS device and allocate enough space for backups. Regularly monitor the available storage space and ensure that it is sufficient for the backup frequency chosen.

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

Although NAS VX1824-V2 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 Uniview VX1824-V2 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 Uniview VX1824-V2 ensure data security and reliability for video game storage?

    The NAS Uniview VX1824-V2 ensures data security and reliability for video game storage through various mechanisms:

    1. Redundant Array of Independent Disks (RAID): The NAS supports various RAID configurations, such as RAID 0, 1, 5, 6, 10, and JBOD. RAID provides data redundancy and improves reliability by distributing data across multiple hard drives. In case of a drive failure, the system can rebuild the data from the remaining drives.
    2. Snapshot Technology: The NAS utilizes snapshot technology to create point-in-time copies of the data. This enables quick recovery in case of accidental deletion, data corruption, or malware attacks. Snapshots can be scheduled regularly to ensure data integrity.
    3. Encryption: The NAS supports AES 256-bit encryption for data stored on the drives. This ensures that even if the drives are stolen or accessed without authorization, the data remains secure and unreadable.
    4. Access Control: The NAS provides granular access control mechanisms, allowing administrators to define user permissions and restrict access to specific folders or files. This prevents unauthorized access and ensures that only authorized users can access and modify the game data.
    5. Backup and Sync: The NAS supports various backup and sync options, including remote replication, cloud backup, and USB copy. These features enable users to create off-site backups and synchronize data across multiple devices, ensuring data reliability and availability.
    6. Network Security: The NAS supports various network security protocols, such as SSL/TLS encryption, firewall, and IP blocking, to protect against unauthorized access and data interception during transmission.
    7. Antivirus and Malware Protection: The NAS can be equipped with antivirus and malware scanning capabilities. This helps in detecting and removing any malicious software that could potentially compromise the data stored on the NAS.

    By implementing these security and reliability features, the NAS Uniview VX1824-V2 ensures that video game data is protected from data loss, unauthorized access, and other potential threats, providing a secure and reliable storage solution.

  • Can the NAS Uniview VX1824-V2 be easily integrated with gaming consoles and PCs to provide seamless access to stored game data?

    The NAS Uniview VX1824-V2 is primarily designed for video surveillance and storage purposes, rather than for gaming. While it is technically possible to connect gaming consoles and PCs to the NAS for storing game data, it may not provide a seamless experience for accessing and utilizing the stored game data.

    Gaming consoles and PCs typically have their own specific methods and requirements for storing and accessing game data. They often rely on internal storage or specialized external storage devices designed for gaming purposes. These devices are optimized for fast data transfer rates and low latency, which may not be the primary focus of a surveillance-oriented NAS like the Uniview VX1824-V2.

    Additionally, gaming consoles and PCs may have their own proprietary file systems or storage formats that might not be fully compatible with the NAS. This can lead to compatibility issues and difficulties in accessing the stored game data.

    If you are looking for a solution to store and access game data seamlessly, it is recommended to use storage devices specifically designed for gaming purposes, such as external hard drives or SSDs that are compatible with gaming consoles and PCs.
