How to recover data from NAS QNAP Turbo Station TS-853DU-RP

QNAP Turbo Station TS-853DU-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 Turbo Station TS-853DU-RP.

How to recover data from NAS QNAP Turbo Station TS-853DU-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 RAID (Redundant Array of Independent Disks) configurations impact data loss in NAS QNAP Turbo Station TS-853DU-RP devices?

RAID configurations in NAS QNAP Turbo Station TS-853DU-RP devices can have a significant impact on data loss. Here are a few ways in which RAID configurations can affect data loss:

  1. Redundancy: RAID configurations, such as RAID 1, RAID 5, RAID 6, provide redundancy by distributing data across multiple disks. This redundancy helps protect against data loss in case of a disk failure. If one or more disks fail, the data can still be accessed from the remaining disks. This ensures that data remains available even if a disk fails, reducing the risk of data loss.
  2. Data reconstruction: In the event of a disk failure, RAID configurations can automatically rebuild or reconstruct the data from the remaining disks. The process involves using parity information or mirroring to recreate the lost data on a new disk. This reconstruction process helps in recovering the data and minimizing the impact of data loss.
  3. Hot spare: Some RAID configurations, like RAID 5 or RAID 6, support the use of a hot spare disk. A hot spare is an extra disk that remains unused until a disk failure occurs. When a disk fails, the hot spare automatically replaces the failed disk, minimizing the downtime and reducing the risk of data loss.
  4. RAID monitoring and notifications: QNAP Turbo Station TS-853DU-RP devices typically come with RAID monitoring and notification features. These features constantly monitor the health of the RAID array and notify the user/administrator in case of any issues or disk failures. This proactive monitoring allows for timely actions to be taken, such as replacing a failing disk, to prevent data loss.

However, it's important to note that RAID configurations do not provide complete protection against data loss. They primarily protect against disk failures, but other factors like accidental deletion, file corruption, or multiple disk failures can still result in data loss. Therefore, it's recommended to have additional data backup strategies in place, such as regular backups to external storage or cloud services, to further safeguard against data loss.

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

Although NAS Turbo Station TS-853DU-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.

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 QNAP Turbo Station TS-853DU-RP network-attached storage keeps QTS (QuTS hero) 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 you explain the RAID configurations supported by the QNAP Turbo Station TS-853DU-RP NAS and how they contribute to data protection?

    The QNAP Turbo Station TS-853DU-RP NAS supports various RAID configurations to provide data protection. Here are the RAID levels supported by this NAS and how they contribute to data protection:

    1. RAID 0: This configuration stripes data across multiple drives without any redundancy. It offers increased performance and storage capacity but provides no data protection. If one drive fails, all data is lost.
    2. RAID 1: In this configuration, data is mirrored across two drives. It provides complete redundancy, as all data is duplicated on both drives. If one drive fails, the other drive can still provide access to all data.
    3. RAID 5: This configuration stripes data across multiple drives, similar to RAID 0, but also includes parity information. Parity information allows for data recovery in case of a single drive failure. If one drive fails, the data can be reconstructed using the parity information and the remaining drives.
    4. RAID 6: It is similar to RAID 5 but with an additional level of redundancy. It uses two sets of parity information, allowing for recovery from the failure of up to two drives simultaneously. RAID 6 provides higher data protection compared to RAID 5.
    5. RAID 10: This configuration combines both mirroring (RAID 1) and striping (RAID 0). Data is mirrored across multiple pairs of drives, and then these pairs are striped for increased performance. RAID 10 provides both redundancy and performance benefits. It can sustain the failure of one drive in each mirrored pair without data loss.

    These RAID configurations contribute to data protection by offering various levels of redundancy and fault tolerance. In case of drive failures, the NAS can continue to provide access to data and ensure data integrity. The specific RAID level chosen depends on the desired balance between data protection, performance, and storage efficiency.
