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 4016 devices against data loss?

Yes, there are several network security measures that can be implemented to safeguard NAS Infortrend EonStor GS 4016 devices against data loss. Here are some recommended measures:

1. Access Control: Implement strong access controls to ensure only authorized users have access to the NAS device. This can include strong passwords, multi-factor authentication, and regular password updates.
2. Firewall: Configure a firewall to protect the NAS device from unauthorized access from external networks. This can help prevent unauthorized access and potential attacks.
3. Encryption: Enable encryption for data stored on the NAS device. This ensures that even if the data is compromised, it cannot be easily accessed or used by unauthorized individuals.
4. Regular Updates: Keep the NAS device's firmware and software up to date with the latest security patches. Regularly check for updates from the manufacturer and apply them as soon as they become available.
5. Network Segmentation: Separate the NAS device from the main network using network segmentation. This can help contain any potential breaches and limit the impact on other devices and systems.
6. Backup and Disaster Recovery: Implement a regular backup and disaster recovery plan to ensure that in case of data loss or device failure, the data can be restored from a backup. Regularly test the backups to ensure their integrity and availability.
7. Intrusion Detection and Prevention: Deploy intrusion detection and prevention systems to monitor network traffic and detect any suspicious activities or potential attacks on the NAS device.
8. User Training and Awareness: Educate users about best practices for network security, such as avoiding suspicious links or attachments, and regularly updating passwords. This can help prevent social engineering attacks and improve overall security awareness.

It is important to note that these measures are general recommendations and may need to be tailored to the specific requirements and capabilities of the Infortrend EonStor GS 4016 device. It is advisable to consult the manufacturer's documentation and guidelines for specific security recommendations for this particular NAS device.

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

Although NAS EonStor GS 4016 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 4016. 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 4016 has 16 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 4016 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.
