Hello @Yugesh Tatikonda

The error message "UserErrorResourceContentionOnVM" indicates that there was a resource contention issue while attempting to back up your Azure VM. This error can occur if there are not enough resources available on the VM or if there are other processes running on the VM that are consuming too many resources.

Here are some steps you can take to troubleshoot the issue:

Check the resource utilization of the VM. You can use the Azure portal or Azure CLI to view the CPU and memory utilization of the VM. If the utilization is high, you may need to increase the size of the VM or optimize the workload running on the VM to reduce resource consumption.

Check if there are any other processes running on the VM that are consuming too many resources. You can use the Task Manager or Resource Monitor on the VM to identify any processes that are consuming a lot of CPU or memory.

Check if there are any other backup or restore operations running on the VM. If there are multiple backup or restore operations running on the VM at the same time, it can cause resource contention issues.

Check if there are any other Azure services or resources running on the same physical hardware as the VM. If there are other services or resources running on the same hardware, it can cause resource contention issues.

Check if there are any network connectivity issues between the VM and the backup vault. You can use the ping command to test connectivity between the VM and the backup vault.

If none of these steps resolve the issue, you may need to contact Microsoft support for further assistance. If I have answered your query, please click "Accept as answer" as a token of appreciation
