How to recover data from Synology RackStation RS2212RP+ / RS2212+ NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

How to recover data from NAS Synology RackStation RS2212RP+ / RS2212+

Synology RackStation RS2212RP+ / RS2212+ NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from RackStation RS2212RP+ / RS2212+.

How to recover data from NAS Synology RackStation RS2212RP+ / RS2212+

Recover data from damaged RAID arrays inaccessible from a computer.

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 the use of multiple NAS Synology RackStation RS2212RP+ / RS2212+ devices in a backup or replication configuration mitigate data loss risks?

Yes, the use of multiple NAS Synology RackStation RS2212RP+ / RS2212+ devices in a backup or replication configuration can help mitigate data loss risks. By setting up a backup or replication system with these devices, you can ensure that your data is stored redundantly across multiple devices.

Here's how it works:

  1. Backup Configuration: You can set up one NAS device as the primary storage location for your data, and then configure another NAS device as a backup target. This backup device can regularly sync with the primary device, ensuring that all data changes are replicated and stored on both devices. In case of data loss on the primary device, you can restore the data from the backup device.
  2. Replication Configuration: In this setup, you can configure multiple NAS devices to replicate data between them. Any changes made on one device will be automatically synchronized and replicated to the other devices. This ensures that your data is stored on multiple devices simultaneously, reducing the risk of data loss.

By using multiple NAS devices in either a backup or replication configuration, you create a redundant storage system that can help protect against various risks such as hardware failures, data corruption, accidental deletions, or other unforeseen events. If one device fails or experiences data loss, you can still access your data from the other devices.

It's important to note that while using multiple NAS devices can mitigate data loss risks, it's still recommended to have additional backup measures in place, such as offsite backups or cloud storage, for even more protection.

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

Although NAS RackStation RS2212RP+ / RS2212+ 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 RS2212RP+ / RS2212+ 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.
