How to Backup and Restore Hyper-V virtual machines:
You can use Hyper-V Manager to create a backup of your virtual machines. The Backup will be saved as a .vhdx file, which you can then copy to another location for safekeeping.
To create a backup of a virtual machine:
- Open Hyper-V Manager and select the virtual machine you want to back up.
- In the Actions pane, click Backup.
- In the Backup Wizard, click Next.
- On the Select Action page, select Copy the virtual machine (create a full backup). Then click Next.
- On the Specify Location page, browse to the location where you want to save the backup file (.vhdx file). Then click Next.
- On the Confirm Selection page, verify your selections and then click Finish
How to Backup and Restore Hyper-V virtual machines from a backup
You need to know a few things before successfully restoring your Hyper-V virtual machines from a backup. This article will show you how to restore a Hyper-V VM from a backup in just a few simple steps.
- To restore your Hyper-V VMs from a backup, you’ll need a backup file (.bkf) of your virtual machine. If you don’t have a backup file, you can create one using the Windows Backup tool.
- Once you have your backup file, open the Backup and Restore tool in Windows and click on “Restore my files.”
- Select the location of your backup file and click “Next.”
- Choose the type of restore you want to perform. If you want to restore all of the files in your Backup, select “Replace existing files.” If you only want to restore certain files, select “Don’t replace existing files.”
- Click “Next” and “Finish” to start the restoration process.
What to do if your Hyper-V virtual machine backup fails
If your Hyper-V virtual machine backup fails, there are a few things you can do to troubleshoot the issue.
- First, check the event viewer for error messages that may indicate what is causing the Backup to fail.
- Next, check the log files for your backup software to see any error messages.
- Finally, if you are using Windows Server Backup, you can try enabling Volume Shadow Copy Services (VSS) on the guest operating system of the virtual machine. This will allow Windows Server Backup to create a snapshot of the guest operating system, which should help back up the virtual machine.
Why you should Backup your Hyper-V virtual machines
- Just like physical servers, virtual machines (VMs) are susceptible to file corruption, hardware failure, and user error.
- And because VMs running on the Microsoft Hyper-V platform store their data in Virtual Hard Disks (VHDs), those VMs are also vulnerable to the same issues that can affect physical hard drives—including accidental deletion and power surges that can lead to data corruption.
- For these reasons, it’s important to create regular backups of your Hyper-V VMs. That way, if something does happen to one of your VMs, you can restore it quickly and get back up and running with minimal downtime.
- In this article, we’ll show you how to create a backup of a Hyper-V VM using Microsoft’s built-in backup tool and how to restore a backed-up VM. We’ll also share some tips on best practices for backing up and restoring Hyper-V VMs.
How to Backup and Restore Hyper-V virtual machines: Troubleshoot issues
The following are common issues you may encounter when you back up or restore Hyper-V virtual machines and how to resolve them.
- Missing or corrupt files in the virtual machine backup
If you find that some files are missing or corrupt in your virtual machine backup, check the following:
- Make sure that Microsoft supports the version of Windows Server you are using for running Hyper-V. You can find a list of supported versions in the “Hyper-V system requirements” section of the Windows Server Tech Center.
- Ensure all the files required for the virtual machine to run are included in the Backup. For example, if you have added any new hardware devices to the virtual machine since it was created, make sure that the drivers for those devices are included in the Backup.
- The virtual machine won’t start after you restore it from a backup
If your virtual machine doesn’t start after you restore it from a backup, check the following:
Ensure you have enough disk space on your computer for the virtual machine to run. The size of the disk space required depends on the size of the virtual hard disk (VHD) file for the virtual machine. For more information, see “Determining how much disk space is needed” in this document’s “Planning for backups” section.
How to Backup and Restore Hyper-V virtual machines: Best practices
Regarding backing up and restoring Hyper-V virtual machines, there are a few best practices to keep in mind. First and foremost, you should always have a backup plan in place before you need it. That way, you can be sure that your data is safe and sound in a disaster.
- Second, you should always test your backups before you rely on them. That way, you can ensure they will work as expected if (and when) you need to use them.
- Finally, it’s important to remember that not all backup and restore solutions are created equal. There are various products on the market, so do your research before settling on one.
How to Backup and Restore Hyper-V virtual machines: Best Resources
Backing up and restoring Hyper-V virtual machines can be complex, depending on the size and number of virtual machines you have. Here are some resources that can help you get started:
- The Microsoft Hyper-V Backup Guide: This guide provides an overview of the different backup options available for Hyper-V and step-by-step instructions for configuring and using each option.
