If you want to log more than just NTBackup events then you can simply leave the Event Source field empty and optionally select all other logs (Security, System, etc.) and severities (Audit Failure, Audit Success). The filter in figure 19 will forward all events logged by the NTBackup source to the Access Database notification.
