In Hyper-V environments, data protection plays a vital role in maintaining business stability. Each virtual machine relies on VHD or VHDX files that store its operating system, applications, and user data, making these files crucial for recovery in case of system errors or disk failure.

With AOMEI Partition Assistant, VHD file backup can be handled easily and safely. The Attach VHD feature allows the virtual hard disk to be mounted and recognized as a local drive, after which the Clone Disk feature can be used to duplicate the entire VHD to another storage device or location. This approach provides a practical way to secure important data without the need to export the whole virtual machine.

By combining these features, AOMEI Partition Assistant offers a convenient and reliable method to back up Hyper-V VHD files, helping ensure data safety and continuous operation in virtual environments.

Step 3. Once the virtual file is selected, you can click "OK" to start attaching the VHD.

Step 4. Once the process is finished, you will see that the VHD is attached successfully.

Stage 2. Clone VHD to HDD now

Once the VHD is attached and recognized by Windows, the next step is to clone it to a physical hard drive to achieve backup VHD file. Using a reliable tool like AOMEI Partition Assistant, you can transfer all data, partitions, and system settings from the virtual disk to the HDD efficiently. Simply select the attached VHD as the source disk, choose your physical HDD as the destination, and start the cloning process. This ensures a complete and safe transfer from virtual to real disk.
