Hello Md Nasir Uddin,

Thank you for your question and for reaching out with your question today.

The error messages you provided indicate that there were failures during the backup process, specifically related to the Microsoft Hyper-V VSS Writer. Here are some steps you can take to troubleshoot and resolve the backup issues:

Check Hyper-V VSS Writer status:
- Open an elevated Command Prompt and run the following command to check the status of the Hyper-V VSS Writer:
```
     vssadmin list writers
```
- Look for the "Microsoft Hyper-V VSS Writer" in the list and check its state. If it shows any state other than "Stable," there might be an issue with the writer that needs to be addressed.
Restart the Hyper-V Virtual Machine Management Service:
- Open the Services console (services.msc).
- Locate the "Hyper-V Virtual Machine Management" service, right-click on it, and select "Restart." This will restart the service and might resolve any temporary issues with the Hyper-V VSS Writer.
Check Hyper-V Integration Services:
- Make sure that the Integration Services are up to date for the virtual machines experiencing backup issues. You can update the Integration Services by selecting "Insert Integration Services Setup Disk" from the Hyper-V Manager's Action menu for each virtual machine.
Check available disk space:
- Ensure that there is sufficient disk space available on the volume where the virtual machine files are stored. Lack of disk space can cause backup failures.
Check event logs for related errors:
- Look for any relevant error messages or warnings in the Event Viewer under "Application" and "System" logs. These logs might provide additional details about the backup failures and point you in the right direction for troubleshooting.
Update Hyper-V and Windows Server:
- Ensure that you have the latest updates and patches installed for Hyper-V and Windows Server 2019. Keeping the system up to date can help resolve known issues and improve stability.
