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 recommended practices for protecting NAS Infortrend JB 360 devices against physical theft or unauthorized access that can lead to data loss?

Yes, there are several recommended practices for protecting NAS Infortrend JB 360 devices against physical theft or unauthorized access that can lead to data loss. Here are some of them:

1. Physical security: Ensure that the NAS device is kept in a secure location, such as a locked server room or cabinet, to prevent unauthorized physical access.
2. Access controls: Implement strong password policies and enforce regular password changes. Use complex passwords that include a combination of uppercase and lowercase letters, numbers, and special characters. Avoid using default or easily guessable passwords.
3. User authentication: Enable user authentication mechanisms, such as two-factor authentication (2FA) or biometric authentication, to add an extra layer of security to the NAS device.
4. Network security: Protect the NAS device by placing it behind a firewall and implementing network security measures like intrusion detection and prevention systems (IDPS), virtual private networks (VPNs), and secure socket layer (SSL) encryption.
5. Firmware updates: Regularly update the firmware of the NAS device to ensure that security vulnerabilities are patched and the device is protected against the latest threats.
6. Backup and disaster recovery: Implement a robust backup strategy to ensure that data is regularly backed up and stored securely off-site. This will help mitigate the impact of data loss in case of theft or unauthorized access.
7. Auditing and monitoring: Enable auditing and monitoring features provided by the NAS device to track and log any suspicious activities or unauthorized access attempts. Regularly review these logs for any anomalies.
8. Employee education: Train employees on the importance of data security, safe browsing habits, and the risks associated with physical theft or unauthorized access. Encourage them to report any suspicious activities or security incidents.

By following these recommended practices, you can significantly enhance the security of your NAS Infortrend JB 360 devices and protect against physical theft or unauthorized access that may lead to data loss.

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

Although NAS JB 360 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 JB 360. 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

JB 360 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 JB 360 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.
