Hi ,
Thanks for reaching out to Microsoft Q&A.
Some generic suggestions to narrow down the issue.
- Verify SQL Server Instance Health: Ensure all SQL instances on your VM are running and healthy. Azure Backup requires all instances to be operational; if any instance is faulty, the VM may not appear as a restore target.
- Check VM Agent Status: Confirm that the Azure VM Agent is installed and up-to-date on your VM. The agent facilitates communication between the VM and Azure Backup services.
- Review Antivirus Settings: Some antivirus programs can interfere with backup and restore operations. Ensure that your antivirus software is not blocking Azure Backup processes.
- Network Configuration: If you've recently modified network settings or firewalls, ensure that your VM can communicate with Azure Backup services.
- Attempt Restore via Different Methods: If the portal continues to present issues, consider using Azure PowerShell or the Azure CLI to initiate the restore process.
If nothing worked, create a support case with azure.
