What is DLNA and how does it work?

DLNA stands for Digital Living Network Alliance. It is a set of guidelines and standards that enable the sharing and streaming of media content between devices over a home network. DLNA allows different devices, such as smartphones, tablets, smart TVs, gaming consoles, and computers, to communicate and share media files seamlessly.DLNA works by establishing a network connection between DLNA-certified devices. These devices must be connected to the same local network, either wired or wireless. Once connected, DLNA devices can discover and communicate with each other using Universal Plug and Play (UPnP) protocols.DLNA uses a client-server architecture, where the DLNA server device stores and shares media content, and the DLNA client devices access and play the shared content. The DLNA server scans and indexes media files, such as photos, videos, and music, and makes them available for streaming. The DLNA client devices can browse and access these shared files, allowing users to stream media from one device to another.DLNA supports various media formats and codecs, ensuring compatibility between different devices. It also provides features like remote control functionality, allowing users to control media playback on DLNA client devices using a DLNA server device or a dedicated DLNA controller application.Overall, DLNA simplifies the process of sharing and streaming media content across multiple devices within a home network, providing a seamless multimedia experience.

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 Digiever 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 utilizing redundant network connections or link aggregation protocols mitigate data loss risks for NAS Digiever DS-165120-RM Pro+ devices?

Yes, utilizing redundant network connections or link aggregation protocols can help mitigate data loss risks for NAS Digiever DS-165120-RM Pro+ devices.

Redundant network connections involve having multiple network interfaces on the NAS device connected to different switches or routers. If one network connection fails, the NAS can automatically switch to another connection, ensuring continuous access to data and reducing the risk of data loss.

Link aggregation protocols, such as Link Aggregation Control Protocol (LACP) or static link aggregation, allow multiple network connections to be combined into a single logical connection. This increases bandwidth and provides redundancy. If one link fails, the traffic is automatically rerouted through the remaining links, preventing data loss.

By implementing redundant network connections or link aggregation protocols, the NAS Digiever DS-165120-RM Pro+ devices can ensure high availability and reliability, minimizing the chances of data loss due to network failures.

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

Although NAS DS-165120-RM Pro+ 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.

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 Digiever DS-165120-RM Pro+ 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.
