Azure backup - OperationNotAllowed : Changes were made to the Virtual Machine
Hiya, I have failed backup jobs on one of our VMs a few days in a row, the error is as follows:
Error Code: UserErrorCrpReportedUserError
Error Message: Backup failed due to an error. For details, see Job Error Message Details
Error Message: "OperationNotAllowed : Changes were made to the Virtual Machine 'Example-Server-Name' while the operation 'Create Restore Point' was in progress. Operation Create Restore Point cannot be completed at this time. Please try again later."
I can't find much on this specific error online. I've tried to do general troubleshooting as per (https://learn.microsoft.com/en-us/azure/backup/backup-azure-troubleshoot-vm-backup-fails-snapshot-timeout and have found the following which according to the guide seems out of place:
- WindowsAgent.AzureSecurityCentre Extension on server is in transitioning state
- No Azure Backup VM Extension visible in virtual machines - server - extensions
- No outbound connectivity to 168.63.129.16 on port 443
Can anyone help me to troubleshoot this issue? Many thanks
