The System Logon Account is not configured in the Backup Exec console.

Resolution:

1. In the Backup Exec console, click on the Network - Logon Accounts menu.

2. Click on System Account and enter credentials of the user account which is to be used as the Default Account in Backup Exec (Figure 1)

3. Set the System Logon Account as the Default Account in Backup Exec.


Run the backup of the VM now and it should complete successfully.

Please note that to browse the ESX server an account with ROOT equivalent permissions on the ESX server should be used.
