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.

Can the use of snapshot or versioning features on NAS QNAP Turbo Station TS-h1886XU-RP R2 devices aid in data recovery after data loss?

Yes, the snapshot or versioning features on NAS QNAP Turbo Station TS-h1886XU-RP R2 devices can aid in data recovery after data loss. These features allow you to take snapshots of your data at different points in time or create versions of your files, which can be extremely helpful in recovering lost or corrupted data.

By regularly creating snapshots or versions, you can easily revert back to a previous state of your data if it gets accidentally deleted, modified, or encrypted by ransomware. This can save you from the hassle of restoring data from backups or relying on more complex data recovery methods.

However, it's important to note that snapshot or versioning features are not a substitute for proper backup strategies. While they can help in certain scenarios, they may not be able to recover data in all cases, such as hardware failures or complete system crashes. Therefore, it's recommended to use these features in conjunction with regular backups to ensure comprehensive data protection and recovery options.

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

Although NAS Turbo Station TS-h1886XU-RP R2 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-h1886XU-RP R2 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 data recovery from a NAS QNAP Turbo Station TS-h1886XU-RP R2 device be done if the disks have been reformatted?
    • Hetman Software
      Hetman Software 19.09.2023 07:59 #

      Yes, data recovery from a NAS QNAP Turbo Station TS-h1886XU-RP R2 device can still be possible even if the disks have been reformatted. When a disk is reformatted, the file system structures are usually overwritten, but the actual data might still be present on the disk until it gets overwritten by new data.

      To recover the data, you can use specialized data recovery software or seek professional data recovery services. These tools or services can scan the disk for any remaining data and attempt to recover it. It is important to note that the success of data recovery depends on various factors, such as the extent of the reformatting and any subsequent data writes to the disk.
