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 Idis 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 device firmware rollback or downgrading impact data loss risks for NAS Idis DR-3516P devices?

Rolling back or downgrading the device firmware of a NAS (Network Attached Storage) device like the Idis DR-3516P can potentially introduce data loss risks. Here's why:

Compatibility Issues: Firmware updates often include bug fixes, security patches, and improvements in functionality. Rolling back or downgrading the firmware may lead to compatibility issues with newer software or hardware components, potentially causing data corruption or loss.
Security Vulnerabilities: Older firmware versions might have known security vulnerabilities that have been addressed in subsequent updates. By downgrading the firmware, you expose your NAS device to potential security risks, including unauthorized access, data breaches, or malware attacks.
Data Incompatibility: Firmware updates sometimes modify the file system or data structures used by the NAS device. Reverting to an older firmware version may render the data incompatible, leading to data loss or the inability to access stored files.
Lack of Support: Manufacturers typically focus their support efforts on the latest firmware versions. By downgrading, you may lose access to technical support, bug fixes, and feature enhancements provided by the manufacturer.

To minimize the risk of data loss, it is generally recommended to keep your NAS device's firmware up to date. However, if you need to rollback or downgrade the firmware, it is crucial to perform thorough backups of your data before proceeding. Additionally, consult the manufacturer's documentation or seek assistance from their support team to ensure a smooth transition and avoid potential data loss.

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

Although NAS DR-3516P 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:

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.
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.
Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
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:

Make sure that you have enough free space to save the image. The image file size usually equals the disk size.
Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.
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.
At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

Where are user’s files stored?

The Idis DR-3516P 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.

  To prevent data recovery from a NAS Idis DR-3516P device in the future, you can take the following measures:
  Regularly backup your data: Implement a robust backup strategy that includes scheduled backups of your important data. This ensures that even if the NAS device fails or data gets corrupted, you have a copy of your data stored elsewhere.
  Use RAID configuration: Configure your NAS device with a RAID (Redundant Array of Independent Disks) setup. RAID provides data redundancy by distributing data across multiple disks, which helps protect against data loss in case of disk failure.
  Implement secure access controls: Set up strong passwords and access controls for your NAS device. Only grant access to authorized users and regularly review and update the user permissions to ensure that only necessary individuals have access to the data.
  Keep your NAS firmware updated: Regularly check for firmware updates provided by the manufacturer and apply them promptly. Firmware updates often include security patches and bug fixes that can help protect your device from vulnerabilities.
  Use encryption: Enable encryption on your NAS device to ensure that even if the physical device is stolen, the data remains inaccessible without the encryption key. This adds an extra layer of protection to your stored data.
  Physically secure the NAS device: Place the NAS device in a secure location that is not easily accessible to unauthorized individuals. Consider using locked cabinets or server rooms with restricted access to prevent physical tampering or theft.
  Implement network security measures: Protect your network by using firewalls, intrusion detection systems, and secure network protocols. Regularly update and patch your network devices to minimize the risk of unauthorized access.
  Train employees on data security best practices: Educate your employees about the importance of data security, including safe file sharing practices, avoiding suspicious links or downloads, and regularly updating their passwords.
  By implementing these measures, you can significantly reduce the risk of data loss or unauthorized access to your NAS device in the future.
