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 Overland Storage 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 deduplication or compression technologies impact data loss risks on NAS Overland Storage SnapServer XSD 40 NAS devices?

Yes, the use of deduplication or compression technologies can impact data loss risks on NAS Overland Storage SnapServer XSD 40 NAS devices.

Deduplication technology eliminates redundant data by identifying and storing only unique data blocks. This can reduce the amount of data stored on the device, resulting in lower storage requirements and potentially reducing the risk of data loss. However, if the deduplication process is not implemented correctly or if there are errors in the deduplication algorithm, it could lead to data loss or corruption.

Compression technology reduces the size of data files by encoding them in a more efficient format. This can also reduce storage requirements and potentially lower the risk of data loss. However, if the compression algorithm used is not reliable or if there are errors in the compression process, it could result in data loss or corruption.

It is important to note that while deduplication and compression technologies can help reduce storage requirements and potentially lower the risk of data loss, they should be implemented carefully and with proper testing to ensure data integrity and minimize the chances of any adverse effects on the NAS device.

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

Although NAS SnapServer XSD 40 NAS 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 Overland Storage SnapServer XSD 40 NAS 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.

      It is possible to recover data from a NAS device that has undergone a file system conversion or re-partitioning, but it can be challenging and may require professional data recovery services.

      When a file system conversion or re-partitioning is performed on a NAS device, the existing data may be overwritten or the file system structures may be modified, making it difficult to access the data using standard methods. However, specialized data recovery techniques can be used to analyze the device and recover the lost data.

      It is important to note that attempting data recovery on your own without proper knowledge and experience can further damage the data and reduce the chances of successful recovery. Therefore, it is recommended to seek the assistance of professional data recovery services who have the expertise and tools to handle such situations.
