What are the different file access levels available on the NAS Idis DR-2116P?

The NAS Idis DR-2116P supports the following file access levels:Administrator: This is the highest level of access that allows full control over the NAS system, including creating and managing user accounts, modifying system settings, and accessing all files and folders.User: Users have limited access to the NAS system. They can create, modify, and delete files and folders within their designated folders, but they cannot access files or folders belonging to other users.Group: Users can be assigned to specific groups, and the group access level allows them to have shared access to certain files and folders. Group members can collaborate on shared files and folders, but they cannot access files or folders outside their group.Public: This access level provides unrestricted access to all files and folders on the NAS system. Any user can access and modify files and folders with public access.Guest: This access level allows anonymous access to specific files and folders without requiring user authentication. Guests can only access files and folders specifically designated for guest access.It is important to note that the specific access levels and their configurations may vary depending on the firmware and settings of the NAS device.

How can you configure file access levels on the NAS Idis DR-2116P?

To configure file access levels on the NAS Idis DR-2116P, you can follow these steps:Connect to the NAS: Open a web browser on a computer connected to the same network as the NAS and enter the NAS IP address in the address bar.Login to the NAS: Enter your username and password to log in to the NAS administration interface.Navigate to the File Access settings: Once logged in, find and click on the 'File Access' or 'Shared Folders' option in the navigation menu. This will take you to the file access configuration page.Create shared folders: To configure file access levels, you first need to create shared folders. Click on the 'Create' or 'Add' button to create a new shared folder. Give it a name, set the desired access permissions (read-only, read-write, etc.), and specify the folder path.Assign user access: After creating the shared folders, you need to assign user access to them. Find the 'User' or 'User Access' section and select the users or user groups that you want to grant access to the shared folders. Set the appropriate access levels for each user or group.Apply changes: Once you have configured the file access levels for the shared folders and assigned user access, click on the 'Apply' or 'Save' button to save the changes.Test file access: To ensure that the file access levels are working as intended, try accessing the shared folders from a computer using the assigned user credentials. Verify that the appropriate access permissions are enforced.Note: The exact steps and options may vary slightly depending on the firmware version and configuration of your NAS. It is recommended to refer to the user manual or documentation provided by the manufacturer for detailed instructions specific to your device.

What are the security implications of different file access levels on the NAS Idis DR-2116P?

The NAS Idis DR-2116P has different file access levels that can impact the security of the system. Here are some security implications associated with these levels:Administrator Access: Administrators have full control over the NAS system, including the ability to modify settings, create or delete user accounts, and access all files and folders. It is crucial to ensure that only trusted individuals have administrator access as they can potentially compromise the entire system if their credentials are compromised.User Access: Users typically have limited access to specific files and folders based on their assigned permissions. However, if a user's account is compromised, an attacker may gain access to the files and folders associated with that user. Therefore, it is important to regularly review and update user permissions to minimize the risk of unauthorized access.Guest Access: Some NAS systems offer a guest access option, allowing users to access specific files or folders without requiring authentication. While this can be convenient for sharing files, it also poses a security risk as anyone with knowledge of the guest access URL or credentials can potentially access sensitive data. It is advisable to disable guest access or restrict it to only non-sensitive data.Public Folder Access: NAS systems often have a public folder where users can store and share files. The security implications of public folder access depend on the sensitivity of the data stored within it. If sensitive information is stored in the public folder, it is recommended to restrict access to authorized users or consider encrypting the files to protect them from unauthorized access.Remote Access: NAS systems may provide remote access capabilities, allowing users to access files and folders from outside the local network. Enabling remote access introduces additional security considerations, such as ensuring secure communication protocols (e.g., SSL/TLS), using strong authentication methods, and regularly updating the NAS firmware to address any security vulnerabilities.Overall, it is essential to carefully configure and manage file access levels on the NAS Idis DR-2116P to ensure that only authorized users have appropriate access to files and folders, minimizing the risk of unauthorized access or data breaches.

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 Idis 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 the use of multiple NAS Idis DR-2116P devices in a backup or replication configuration mitigate data loss risks?

Yes, the use of multiple NAS Idis DR-2116P devices in a backup or replication configuration can help mitigate data loss risks.

By setting up multiple devices in a backup or replication configuration, you create redundancy in your data storage system. This means that if one device fails or experiences data loss, you can still retrieve your data from the other devices.

Additionally, using multiple devices allows for distributed data storage, which can enhance data protection. You can store copies of your data on different devices, ensuring that even if one device is compromised, the data remains safe on the others.

Furthermore, NAS devices often provide features like RAID (Redundant Array of Independent Disks) that can help protect against data loss. RAID configurations distribute data across multiple disks, providing redundancy and increasing the overall reliability of the storage system.

However, it's important to note that while using multiple NAS devices in a backup or replication configuration can mitigate data loss risks, it does not completely eliminate the possibility of data loss. Other factors such as hardware failures, natural disasters, or human errors can still pose risks to your data. Therefore, it's crucial to have a comprehensive backup strategy that includes offsite backups, regular data verification, and other best practices to ensure data protection.

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

Although NAS DR-2116P 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:

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.
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.
Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
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.
