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 Infortrend also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Are there any specific network security measures to implement for safeguarding NAS Infortrend EonStor GS 3060 devices against data loss?

Yes, there are several network security measures that can be implemented to safeguard NAS Infortrend EonStor GS 3060 devices against data loss. Here are some recommendations:

1. Secure Network Configuration: Ensure that the NAS device is connected to a secure network that is isolated from untrusted networks or the internet. Use firewalls to restrict access to only authorized systems and users.
2. Strong Authentication: Implement strong authentication mechanisms such as complex passwords, two-factor authentication (2FA), or even biometric authentication to prevent unauthorized access to the NAS device.
3. Regular Firmware Updates: Keep the NAS device's firmware up to date with the latest security patches and updates provided by the manufacturer. This helps in addressing any known vulnerabilities and improving the overall security of the device.
4. Access Control Lists (ACLs): Utilize access control lists to define and restrict access permissions for different users or groups. This ensures that only authorized users can access and modify the data stored on the NAS device.
5. Encryption: Enable encryption for data at rest and data in transit. This ensures that even if the NAS device is compromised, the data remains protected and unreadable to unauthorized individuals.
6. Backup and Disaster Recovery: Implement regular backups of the data stored on the NAS device and store them in secure offsite locations. This ensures that in case of data loss or device failure, the data can be restored from backups.
7. Intrusion Detection and Prevention Systems (IDPS): Deploy IDPS solutions to monitor network traffic and detect any potential security threats or intrusions. This helps in identifying and mitigating attacks before they can cause any damage.
8. Network Segmentation: Implement network segmentation to isolate the NAS device from other parts of the network. This prevents lateral movement and limits the potential impact of a security breach.
9. User Education and Awareness: Train users on best practices for network security, such as avoiding phishing emails, using strong passwords, and being cautious when accessing the NAS device remotely.
10. Physical Security: Ensure physical security measures are in place to protect the NAS device from theft or unauthorized access. This includes securing the physical location, using surveillance cameras, and restricting physical access to authorized personnel only.

It is important to note that these measures should be implemented in combination with each other to provide a comprehensive security posture for the NAS device. Additionally, consulting the manufacturer's documentation and seeking professional advice can also help in implementing the most appropriate security measures for your specific environment.

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

Although NAS EonStor GS 3060 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 Infortrend EonStor GS 3060. 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 Infortrend

EonStor GS 3060 has 60 HDD slots, and it supports the following array types:

• RAID 0;
• RAID 1;
• RAID 5;
• RAID 6;
• RAID 50;
• RAID 60;
• JBOD;

NAS supports:

• exFAT, VFAT, FAT 12 / 16 / 32;
• NTFS / ReFS;
• APFS / HFS+;
• Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
• VMFS / HikvisionFS;

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 Infortrend EonStor GS 3060 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.
