How to Backup Virtual Machines with AOMEI Cyber Backup

Due to system updates, virus attacks, etc., your virtual machine system may crash. It is very time-consuming to rebuild the virtual machine system and all applications. Therefore, by regularly backing up the virtual machine, you can quickly restore the previous state when needed. With AOMEI Cyber Backup, you can easily do all this.

In this article, we will introduce how to create backups of virtual machines VMware ESXi and Hyper-V with AOMEI Cyber Backup. AOMEI Cyber Backup provides a convenient and reliable solution for centralized backup management of multiple devices, without installation any agent on the virtual host device. With the program, you can back up all devices to a local or network location. And, you can easily monitor and manage the backup of the equipments via central control server.

How to Create Backups of Virtual Machines

Prerequisites for VM backup:

  • Computer with AOMEI Cyber Backup installed
  • VMware or Hyper-V host
  • Local disk or network share to store backup files

Currently, VMware ESXi Backup and Hyper-V Backup are supported. Here we take backup of VMware ESXi as an example. For the usage environment supported by AOMEI Cyber Backup, please refer to here.

1. Click "Backup Task" on the left menu bar, select "Backup Task". Click "Create New Task" to open the task creating page.

Create New Task

2. Select "Backup Type", you can choose VMware ESXi Backup or Hyper-V Backup.

Select Device Type

3. Set a "Task Name". It will have a default name. You can edit the name of the task.

Set Task Name

4. Select "Device Name". The host you have added and all virtual machines under the host will be listed.

Tips: If you haven't added any devices, there won't be any virtual machines listed here. You can click the "Add Device" button in the lower left corner to jump to the interface for adding devices.

Select Device Name

Then you can select one or multiple virtual machines under the host for backup.

Select Virtual Machines


  • When a virtual machine has already been backed up in an existing backup task, you can’t select the virtual machine again to create a new task. If you want to re-create backup task for it, please delete the virtual machine from the existing backup task first.
  • You can select multiple virtual machines for backup, but only one virtual machine can be backed up at a time, and the next one will not be backed up until the previous backup is completed.

5. Select "Target" to save backups.

Select Target

You can select a local or network path.

Added storage: It will list all added backup target. You can select the backup target without adding it again.

Add a new local storage: It will list the local directory of this computer with AOMEI Cyber Backup installed , then you can select a location as backup target.

Add a new network storage: You can type into a network path (such as:\data), then fill in username and password of the network path to add. After that, you can continue to select a folder of the network path as backup target.

Tips: You can also add and manage target locations in Target Storage.

7. Set Backup Cleanup.

Backup Cleanup helps you automatically remove history backup versions based on rule to save storage space. After activating this option, you can let AOMEI Cyber Backup clean up automatically without worrying about backup failure due to disk space being full.

Generally, the backup cleanup is enabled by default. You can change the backup cleanup based on your needs, or disable it. For more details about this function, please check Backup Cleanup.

Now that we've covered the VMware ESXi backup process, the same goes for backing up Hyper-V. 

You can see the backup details in Backup Tasks, and you can continue to do full backup, incremental backup or differential backup. You can also manage backup tasks here, like edit or delete the tasks.

If there is an abnormality in the virtual machine system, you can restore it to the previous state.
