Synology RackStation RS214 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 RS214.

How to recover data from NAS Synology RackStation RS214

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.

How does a NAS Synology RackStation RS214 device store and manage data?

The Synology RackStation RS214 is a network-attached storage (NAS) device that stores and manages data using various mechanisms. Here's how it typically works:

  1. Hard Drives: The RS214 comes with two drive bays, and you can install two hard drives or solid-state drives (SSDs) in these bays. The device supports various storage capacities, and you can configure the drives in different RAID configurations (e.g., RAID 0, RAID 1, JBOD) depending on your requirements.
  2. File System: The RS214 uses the Synology DiskStation Manager (DSM) operating system, which supports multiple file systems. By default, it uses the Btrfs (B-Tree File System) or EXT4 file system, depending on your configuration. These file systems provide data integrity, snapshots, and other advanced features.
  3. Data Management: The RS214 offers various data management features. You can create shared folders to organize your data and assign different access permissions to users or groups. It also supports file-level and folder-level encryption to ensure data security.
  4. RAID Protection: If you configure the RS214 in a RAID configuration (e.g., RAID 1), it provides data redundancy. This means that even if one drive fails, your data remains accessible, and you can replace the faulty drive without downtime or data loss.
  5. Backup and Sync: The RS214 supports various backup and synchronization mechanisms. You can schedule regular backups to external drives, other NAS devices, or cloud storage services. It also offers file syncing capabilities, allowing you to keep data synchronized across multiple devices.
  6. Remote Access: Synology NAS devices come with built-in remote access features. With the RS214, you can access your data remotely using Synology's QuickConnect service or by setting up a virtual private network (VPN) connection. This enables you to access and manage your data from anywhere securely.
