How to recover data from QNAP TVS-1272XU-RP 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 QNAP TVS-1272XU-RP

QNAP TVS-1272XU-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-1272XU-RP.

How to recover data from NAS QNAP TVS-1272XU-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 data fragmentation impact the read and write speeds, and potential data loss on NAS QNAP TVS-1272XU-RP devices?

Data fragmentation can have several impacts on read and write speeds, as well as potential data loss, on NAS QNAP TVS-1272XU-RP devices. Here are some ways data fragmentation can affect these aspects:

  1. Read and Write Speeds:
  • Increased seek time: Fragmented data is scattered across different physical locations on the storage drives. This leads to increased seek time for the drives to locate and retrieve the fragmented data, resulting in slower read and write speeds.
  • Reduced sequential access: Fragmented data breaks the continuity of sequential data access. As a result, the drives need to constantly seek and read data from different locations, leading to decreased sequential access speeds.
  • Fragmented file allocation: Fragmentation can cause files to be split into multiple fragments, resulting in additional overhead for the drives to access and process these fragments. This can further slow down read and write speeds.
  1. Data Loss:
  • Increased susceptibility to disk errors: Fragmentation can exacerbate the impact of disk errors. If a disk sector containing a fragment of data becomes corrupt or unreadable, it can lead to data loss or corruption of the entire file or folder.
  • Difficulty in data recovery: In case of data loss or corruption, fragmented data can make it more challenging to recover the lost data. Fragmented files may have scattered fragments across multiple locations, making it harder for data recovery tools to piece them together accurately.

To mitigate these issues, it is recommended to regularly defragment the storage drives on QNAP TVS-1272XU-RP devices. Defragmentation rearranges fragmented data, consolidating it into contiguous blocks, thereby improving read and write speeds. Additionally, regular backups should be maintained to minimize the risk of data loss.

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

Although NAS TVS-1272XU-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.

NAS supports:

  • ZFS;
  • EXT4;
  • EXT3;
  • exFAT;
  • FAT32 (External Disk Only);
  • NTFS (External Disk Only);
  • HFS+ (External Disk Read Only);

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 TVS-1272XU-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.

    Are there any specific file systems used in NAS QNAP TVS-1272XU-RP devices that may affect data recovery?
    • Hetman Software
      Hetman Software 15.09.2023 23:59 #

      The QNAP TVS-1272XU-RP NAS devices typically use the QTS (QNAP Turbo NAS System) operating system, which supports multiple file systems. The default file system used is EXT4, which is a widely used and reliable file system. However, QNAP also supports other file systems such as NTFS, FAT32, HFS+, and exFAT, depending on the specific requirements of the users.

      When it comes to data recovery, the file system used can affect the process. For example, if the device is using the EXT4 file system, there are several data recovery tools available that can help recover deleted or lost files. However, if the device is using a different file system like NTFS or HFS+, the data recovery process may require specific tools that are compatible with those file systems.

      It's worth noting that regardless of the file system used, data recovery from a NAS device can be a complex task and may require professional assistance. It's always recommended to have a backup strategy in place to avoid data loss and to consult with a data recovery specialist if needed.
