- Interfaces
You can configure the interface to copy exception (snapshot) data or archive data. For best performance, configure a separate instance of the interface for each source Data Archive. If you intend to copy both archive and exception data, configure separate instances of the interface for each type of data. Data throughput (events per second) can be limited by network quality or system resources.
