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.

How can conducting regular backups on external storage devices mitigate data loss risks for NAS Infortrend EonStor DS 3012 devices?

Conducting regular backups on external storage devices can mitigate data loss risks for NAS Infortrend EonStor DS 3012 devices in the following ways:

  1. Data redundancy: By regularly backing up data to an external storage device, you create a duplicate copy of your important files. In case of any data loss or corruption on the NAS device, you can restore the data from the backup, ensuring that your files are safe.
  2. Protection against hardware failures: NAS devices, like any other hardware, can experience failures. Conducting regular backups on external storage devices ensures that even if the NAS device fails, your data remains intact on the backup storage. You can easily restore the data to a new NAS device or any other system.
  3. Protection against accidental deletion or user errors: Sometimes, data loss can occur due to accidental deletion or user errors. Regular backups on external storage devices provide a safety net in such cases. If any data is accidentally deleted or modified incorrectly, you can retrieve the original version from the backup.
  4. Protection against malware and ransomware attacks: NAS devices are vulnerable to malware and ransomware attacks, which can encrypt or delete your data. Regular backups on external storage devices ensure that even if your NAS device gets infected, you have a clean copy of your data that is not affected by the attack. You can restore the data after removing the malware or ransomware.
  5. Disaster recovery: In case of a natural disaster, fire, theft, or any other catastrophic event that damages or destroys your NAS device, having regular backups on external storage devices ensures that your data is not lost forever. You can recover your data from the backup and continue your operations.

It is important to follow best practices for backups, such as keeping multiple copies of backups, storing them in separate physical locations, and regularly verifying the integrity of the backups to ensure their effectiveness in mitigating data loss risks.

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

Although NAS EonStor DS 3012 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.

Questions and answers

  • 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 of digital media content between devices within a home network. DLNA allows devices like smartphones, tablets, computers, smart TVs, and gaming consoles to seamlessly communicate and stream media files such as photos, videos, and music.

    DLNA works by utilizing the Universal Plug and Play (UPnP) protocol to establish a connection between devices on the same network. This allows the devices to discover and communicate with each other. DLNA-certified devices act as both servers and clients. A server device stores and shares media content, while a client device can access and play the shared media.

    To initiate DLNA, the server device must be connected to the network and have the media files stored locally or on external storage. The server then advertises its availability to other devices on the network. The client devices can then browse and access the available media content, and stream it directly to their own screens or speakers.

    DLNA supports various media formats and codecs, ensuring compatibility across different devices. It also allows for controlling playback, volume, and other features remotely from a client device. DLNA operates over wired or wireless connections, making it convenient for users to access and enjoy their media content throughout their home network.
