How can I configure file access levels on the QNAP TVS-872XT NAS for different users or groups?

To configure file access levels on the QNAP TVS-872XT NAS for different users or groups, follow these steps:Log in to the QNAP NAS web interface using your admin credentials.Go to 'Control Panel' and click on 'Shared Folders.'Create a new shared folder or select an existing one that you want to configure access levels for.Click on 'Edit' next to the shared folder you selected.In the 'Permissions' tab, you will see a list of existing users and groups with their respective access permissions.To add a new user or group, click on the '+' icon.In the 'Add User/Group' window, select either 'User' or 'Group' from the dropdown menu.Enter the name of the user or group you want to add and click 'OK.'Once the user or group is added, you can set their access permissions by checking the boxes for Read, Write, or Deny.You can also set advanced permissions by clicking on the 'Advanced Permissions' button. This allows you to configure more granular access control settings.After setting the desired access levels, click 'Apply' to save the changes.Repeat the above steps for each user or group you want to configure access levels for.Once the access levels are configured, users or groups will have the specified permissions when accessing the shared folder.Remember to regularly review and update access levels to ensure the security and integrity of your files.

Can you explain the permissions and restrictions associated with each file access level on the QNAP TVS-872XT NAS?

The QNAP TVS-872XT NAS provides several file access levels with different permissions and restrictions. Here is a breakdown of each access level:Admin: The admin access level has full control over all aspects of the NAS. This includes the ability to create, modify, and delete files and folders, manage users and groups, adjust system settings, and install or uninstall applications.Read/Write: Users with the read/write access level can view, create, modify, and delete files and folders. They can also upload and download files, but they do not have administrative privileges to manage system settings or install applications.Read Only: Users with the read-only access level can only view and download files and folders. They cannot create, modify, or delete any content on the NAS.Deny Access: This access level restricts users from accessing any files or folders on the NAS. They will not be able to view or download any content.Custom: The custom access level allows administrators to define specific permissions for individual users or groups. This level provides granular control over file and folder access, allowing administrators to set different permissions for different users or groups.It's important to note that access levels can be assigned to individual users or groups, ensuring that multiple users can have different levels of access to the same files and folders. This allows for effective collaboration and data security on the QNAP TVS-872XT NAS.

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

What is a NAS QNAP TVS-872XT (Network Attached Storage) device?

The QNAP TVS-872XT is a Network Attached Storage (NAS) device. NAS is a file-level storage system that allows multiple users and devices to access and share data over a network. The TVS-872XT is produced by QNAP Systems Inc., a Taiwanese company specializing in network-attached storage and surveillance solutions.

The TVS-872XT is a high-performance NAS device designed for professional and creative users. It features an Intel Core i5 quad-core processor, up to 64GB DDR4 RAM, and eight drive bays for installing hard drives or SSDs. It supports various RAID configurations for data redundancy and protection.

The device offers a wide range of connectivity options, including multiple Gigabit Ethernet ports, USB 3.1 Gen2 ports, and Thunderbolt 3 ports. Thunderbolt 3 allows for high-speed data transfer and daisy-chaining of devices. It also supports 10GbE connectivity for faster network speeds.

The TVS-872XT runs on QNAP's QTS operating system, which provides a user-friendly interface for managing and accessing files, as well as a variety of applications and services. It supports features such as file sharing, remote access, data backup, virtualization, and multimedia streaming.

Overall, the QNAP TVS-872XT is a powerful and versatile NAS device that offers high-performance storage and advanced features for professional users who require reliable and efficient file sharing and data management.

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

Although NAS TVS-872XT 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.

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 QNAP TVS-872XT. 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.

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:

Make sure that you have enough free space to save the image. The image file size usually equals the disk size.
Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.
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.
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 QNAP TVS-872XT network-attached storage keeps QTS (QuTS hero) 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.
