[Solved] Recover Data from Ext4/3/2 NAS/Linux Device

What Is Ext4 Used for?

Ext4 The evolution of the most used Linux file system, Ext3, is Ext4, which is a deeper improvement. Unlike Ext3, which mainly added journaling to Ext2, Ext4 modifies the data structures that store file data, resulting in a filesystem with improved design, performance, reliability, and features.

Ext4 ensures that file system metadata is correctly written and ordered on your storage device, preventing performance issues when write caches lose power, especially for applications that rely on disk performance.

• You are using a NAS server with Ext4 or BTRFS file systems on its disks.
• You're using a database that requires the ext4 file system to achieve optimal performance.
• Your system is running on Linux and the disks are typically formatted with the Ext4 file system.
• You are using QNAP and Synology...

The Ext4 file system is commonly used in Network Attached Storage (NAS) and Linux environments, but users often experience data loss due to accidental deletion, formatting, and file system errors. To address these issues and recover Ext4 data, two solutions are presented in this post.

Part 1. Recover Data from Ext4 NAS Device in Windows 11/10

Regardless of the brand, such as QNAP, Synology, Western Digital, or NETGEAR, the file system of the device is Ext4. If you've accidentally deleted files from your NAS or formatted it to upgrade to a larger one, you can recover your data using Qiling RAID recovery software.

This hard disk data recovery software can recover both recently deleted files and those lost long ago, as well as restore corrupted files. It can also read and recover information from an inaccessible drive, saving your deleted or damaged data and offering several useful features.

Step 1. Select a NAS server and start recovering.

Download and install Deep Data Recovery on your Windows 11/10 64-bit computer. When you open this software, select "NAS Recovery" and it will automatically list all NAS servers, allowing you to choose your target device and click "Scan" to proceed.

Step 2. Enable SSH service on the NAS server.

To enable remote access, go to the "Control Panel > Terminal & SNMP" and check the box next to "Enable SSH service". Note the port number for remote access. Then, in Deep Data Recovery, click "Next" after viewing and remembering the port number.

Step 3. Connect to the NAS server remotely.

This software automatically detects your IP and Port, requiring only username and password input. If the IP or Port is incorrect, you can manually correct them. After inputting the required information, click "Connect Now" to proceed.

Step 4. Recover lost/deleted NAS data

Qiling data recovery software will connect to your NAS and start a scanning process. After the scan, it will display all deleted, lost, or existing files on your NAS server, allowing you to view and potentially recover your data.

To find lost files on your hard drive, use the "Filter" feature or search for files and folders. Select the desired NAS files and click "Recover" to save them to a new location.

Part 2. Restore Data from Linux Ext4/3/2 Partition in Windows 10

To recover data from Ext4, Ext3, and Ext2 Linux partitions in Windows, use data recovery software that specifically supports Ext4 file system, making Ext4 data recovery possible.

Qiling data recovery software can help you retrieve Linux Ext4 data on a Windows computer. To recover data from Ext4, Ext3, and Ext2 Linux partitions on Windows with Qiling, you need to follow these steps:

• 1. Download and install Deep Data Recovery on your Windows computer.
• 2. Connect the hard drive with the Ext4 partition to the Windows computer. Since Windows does not natively support Ext4, you will need to install a third-party driver or use a tool like EaseUS to read the Ext4 partition.
• 3. Follow these simple steps below:

• Free Download
• Windows 11/10/8/7, 100% Secure

Step 1. Run Deep Data Recovery. Choose file types and click "Next" to start the recovery process.

Step 2. Select the partition where the lost files were stored and click "Scan" to recover them. The software supports various file systems, including FAT, exFAT, NTFS, NTFS5, ext2, ext3, HFS+, and ReFS.

Step 3. To quickly locate lost data from numerous scan results, you can utilize the filter or search function.

Step 4. You can preview files before recovering them, and then select all desired data and click "Recover" to restore files from existing partitions. However, it's essential not to save the recovered files to the partition where you lost the data.

Conclusion

Accessing and recovering Linux Ext4 data on a Windows computer is straightforward with a reliable data recovery tool. Since Windows can't directly read Linux partitions, a data recovery software is necessary. If issues persist, a manual RAID recovery service can be an option.
