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 Lenovo 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 remote access to NAS Lenovo ThinkSystem SR645 Rack Server devices pose additional data loss risks?

Remote access to NAS Lenovo ThinkSystem SR645 Rack Server devices can pose additional data loss risks if proper security measures are not in place. Here are some potential risks:

Unauthorized access: If remote access is not properly secured with strong passwords, multi-factor authentication, and encryption, there is a risk of unauthorized individuals gaining access to the NAS device. This can lead to data loss or theft.
Malware and hacking: Remote access can provide an entry point for malware or hacking attempts. Attackers can exploit vulnerabilities in the remote access software or use brute force attacks to gain control of the NAS device. Once compromised, data can be deleted, encrypted, or stolen.
Human error: Remote access increases the chances of human error, such as accidental deletion or misconfiguration of settings. If data is not properly backed up or protected, these errors can lead to permanent data loss.
Network vulnerabilities: Remote access relies on network connections, which can introduce vulnerabilities. If the network is not properly secured, attackers can intercept or manipulate data during transmission, leading to data loss or corruption.

To mitigate these risks, it is important to implement strong security practices:

Use strong passwords and enable multi-factor authentication for remote access.
Keep the NAS device and remote access software up to date with the latest security patches.
Implement encryption for remote access connections to protect data in transit.
Restrict remote access to trusted IP addresses or use VPNs to create secure connections.
Regularly back up data to an off-site location to minimize the impact of data loss.
Train employees on best practices for remote access and data security to minimize human errors.

By implementing these security measures, the risks associated with remote access to NAS Lenovo ThinkSystem SR645 Rack Server devices can be significantly reduced.

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

Although NAS ThinkSystem SR645 Rack Server 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:
