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 Raidon 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 regular vulnerability assessments and security audits help identify and mitigate potential data loss risks for NAS Raidon InTANK iR2824 devices?

Regular vulnerability assessments and security audits can help identify and mitigate potential data loss risks for NAS Raidon InTANK iR2824 devices in the following ways:

1. Identifying Vulnerabilities: Vulnerability assessments can help identify any weaknesses or vulnerabilities in the NAS device's firmware, operating system, or network configuration. This can include outdated software versions, misconfigurations, or known security flaws that could potentially lead to data loss.
2. Patch Management: Regular security audits can ensure that the NAS device's firmware and software are up to date with the latest security patches. This helps mitigate the risk of exploitation through known vulnerabilities and reduces the chances of data loss.
3. Network Security: Assessing the network security around the NAS device can help identify any potential risks, such as unauthorized access, weak passwords, or insecure network protocols. By implementing proper network security measures, such as strong passwords, encryption, and secure protocols, the risk of data loss can be significantly reduced.
4. Access Control: Regular audits can review the access control mechanisms in place for the NAS device. This includes user permissions, authentication methods, and password policies. By ensuring that only authorized users have access to the device and data, the risk of data loss due to unauthorized access or insider threats can be minimized.
5. Data Backup and Recovery: Vulnerability assessments and security audits can also evaluate the effectiveness of the data backup and recovery processes for the NAS device. This includes reviewing backup configurations, testing the restoration process, and ensuring that backups are stored securely offsite. By having proper backup mechanisms in place, the impact of data loss can be mitigated, as data can be restored from backups in case of any incidents.
6. Physical Security: Security audits can assess the physical security measures in place for the NAS device, such as access controls, surveillance systems, and environmental controls. By securing the physical environment where the device is located, the risk of physical damage or theft that could lead to data loss can be reduced.

By regularly conducting vulnerability assessments and security audits, organizations can proactively identify and mitigate potential data loss risks for NAS Raidon InTANK iR2824 devices, ensuring the security and integrity of their data.

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

Although NAS InTANK iR2824 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.

   How to Order Remote Data Recovery

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Raidon InTANK iR2824. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

How to recover data from a Raidon

InTANK iR2824 has 3 HDD slots, and it supports the following array types:

• RAID 0;
• RAID 1;
• RAID 5;
• JBOD;

NAS supports:

• APFS / HFS+;
• Ext2 / Ext3 / Ext4;

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 Tools – Save 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.

   

4. 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 Raidon InTANK iR2824 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.
