Hello,
Thank you for your question.
The error message "Microsoft Azure Backup encountered an internal error" is quite generic and could be caused by a variety of issues. Here are some general steps you can take to troubleshoot:
Check Azure Status: Check the Azure status page to see if there are any ongoing issues with Azure Backup service in the region where your resources are located.
Check Operation Details: If you're seeing this error in response to a specific operation, check the operation details for more information. This might give you more context about what's going wrong.
Retry the Operation: Sometimes, transient issues can cause operations to fail. Try retrying the operation to see if the problem persists.
Check Resource Health: Check the health of the resources involved in the operation. If a resource is unhealthy, it might be causing the operation to fail.
Review Activity Log: Review the activity log for the resources involved in the operation. The activity log might contain more detailed error messages that can help you diagnose the problem.
