We are using Microsoft Azure Backup to backup our server. Our backup is passing on 4 out of 5 drives, but consistently failing on the one. All that the Microsoft Azure GUI agent tells me though is that it failed. Where can I find the logs to further diagnose this issue? Thanks in advance.
Take a look at the cloudbackup\operational event log on the client. Additional logs are in C:\program files\Microsoft Azure Recovery Services Agent\Temp. In that directory take a look at CBEngineCurr.errlog, which should contain the step by step details on issues.
Another way you view the Microsoft Azure Backup Agent logs is accessing. Server Manager > Diagnostics > Event Viewer > Application and services log > CloudBackup > Operational. You will have a record of logs for the service
