When trying to start the Veeam Backup Service you get the following error in the Application Event Log
Service cannot be started. System.OperationCanceledException: The operation was canceled.
at Veeam.Backup.DBCreator.BackupDatabaseDeployer.CanDeploy(IDatabaseVersion databaseVersion)
at Veeam.Backup.DBCreator.BackupDatabaseDeployer.DatabaseDeploy(List`1 inDeployChangedOptions)
at Veeam.Backup.Service.CVbServiceImpl..ctor(CVbEnvironment env, CTerminationMediator terminator)
at Veeam.Backup.Service.CVeeamBackupSvc.OnStart(String args)
at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)
And the error below in the System Event Log
The Veeam Backup Service service terminated with the following error: An exception occurred in the service when handling the control request.
This is likely caused by a change of Hostname of the server hosting the SQL Database.
To change this update the SqlServerName key here – Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication
