Abstract: Disclosed is a server. A server according to an embodiment of the present disclosure includes a gatherer configured to receive a file collection list from an external server, at least one wagon configured to collect data from the external server based on the file collection list received from the gatherer, a historian file configured to store a transmission history or a file collection history, and a destination folder configured to store the data collected by the wagon, and the wagon is further configured to, when an error occurs during data collection, collect data for a file again in which the error occurs. Accordingly, it is possible to quickly collect data again when an error occurs.
