How to recover data from NAS QNAP TVS-471U-RP

QNAP TVS-471U-RP NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from TVS-471U-RP.

How to recover data from NAS QNAP TVS-471U-RP

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 QNAP 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 quality of service (QoS) settings impact data transfer reliability on NAS QNAP TVS-471U-RP devices?

Quality of Service (QoS) settings can have a significant impact on data transfer reliability on NAS QNAP TVS-471U-RP devices. QoS allows you to prioritize certain types of network traffic over others, ensuring that critical or time-sensitive data receives the necessary bandwidth and resources.

Here are a few ways QoS settings can impact data transfer reliability:

  1. Bandwidth allocation: QoS settings allow you to allocate a specific amount of bandwidth to different applications or services. By prioritizing data transfer protocols or applications, you can ensure that they receive a sufficient amount of bandwidth, preventing congestion and improving reliability.
  2. Traffic prioritization: QoS settings enable you to prioritize certain types of traffic over others. For example, you can prioritize data transfers over web browsing or streaming services. By giving data transfers higher priority, you ensure that they are less likely to be affected by other network activities, improving reliability.
  3. Packet prioritization: QoS settings also allow you to prioritize individual packets based on their importance. For example, you can prioritize packets related to file transfers or backups over less critical packets. This prioritization ensures that crucial data packets are delivered promptly, reducing the chances of data loss or transfer interruptions.
  4. Traffic shaping: QoS settings can shape or limit the bandwidth usage of specific applications or services. By setting maximum bandwidth limits for certain applications, you can prevent them from monopolizing the available bandwidth, ensuring fair distribution and improving reliability for other data transfers.
  5. Latency management: QoS settings can help manage network latency by prioritizing real-time traffic like VoIP or video conferencing. By minimizing latency, you improve the responsiveness and reliability of data transfers, particularly for time-sensitive applications.

Overall, proper QoS settings on QNAP TVS-471U-RP devices can optimize network resources, prevent congestion, and prioritize critical data transfers, resulting in improved reliability and performance.

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

Although NAS TVS-471U-RP 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.
