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 Synology 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 improper handling or maintenance of NAS Synology RackStation RS2416RP+ / RS2416+ device hardware lead to data loss?

Yes, improper handling or maintenance of the NAS Synology RackStation RS2416RP+ / RS2416+ device hardware can potentially lead to data loss. The hardware components of the device, such as hard drives, power supply units, and fans, need to be properly maintained and handled to ensure the integrity and safety of the data stored on the NAS.

For example, mishandling or dropping the device can cause physical damage to the hard drives, leading to data corruption or loss. Similarly, inadequate cooling due to improper fan maintenance or ventilation can result in overheating, which can damage the hard drives and cause data loss.

It is crucial to follow the manufacturer's guidelines for handling, maintenance, and regular backups to minimize the risk of data loss. Additionally, proper security measures should be in place to protect against unauthorized access or accidental deletion of data.

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

Although NAS RackStation RS2416RP+ / RS2416+ 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.

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:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. 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.

Where are user’s files stored?

The Synology RackStation RS2416RP+ / RS2416+ network-attached storage keeps DSM (DiskStation Manager) 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.

  • What are the recommended security settings for the NAS Synology RackStation RS2416RP+ / RS2416+?

    Here are some recommended security settings for the NAS Synology RackStation RS2416RP+ / RS2416+:

    1. Change the default administrator password: Upon initial setup, change the default password to a strong and unique one to prevent unauthorized access.
    2. Enable two-factor authentication (2FA): Enable 2FA to add an extra layer of security to your NAS. This will require users to provide a second form of verification, such as a code from a mobile app, in addition to their password.
    3. Keep the NAS firmware up to date: Regularly update the NAS firmware to ensure that any security vulnerabilities are patched. Enable automatic updates if available.
    4. Enable firewall: Enable the built-in firewall on the NAS to restrict incoming and outgoing traffic. Configure the firewall rules to allow only necessary services and block any unnecessary ports.
    5. Disable unnecessary services: Disable any services that are not required for your specific usage scenario. This reduces the attack surface and minimizes potential vulnerabilities.
    6. Use strong and complex passwords: Enforce strong password policies for all users. Use a combination of uppercase and lowercase letters, numbers, and special characters. Avoid using easily guessable passwords or common words.
    7. Enable account lockout policy: Configure the NAS to lock user accounts after a certain number of unsuccessful login attempts. This helps prevent brute-force attacks.
    8. Enable network encryption: Enable SSL/TLS encryption for network connections to secure data transmission between the NAS and connected devices. This is particularly important when accessing the NAS remotely over the internet.
    9. Regularly backup data: Implement a backup strategy to regularly backup critical data stored on the NAS. This ensures that data can be recovered in case of any security incidents or hardware failures.
    10. Monitor system logs: Regularly review system logs for any suspicious activities or unauthorized access attempts. Enable email notifications for critical events to stay informed about potential security issues.

    Remember that security is an ongoing process, and it is important to stay updated with the latest security best practices and recommendations provided by the manufacturer.
