It is a common requirement to make data that lives on one server available on another. You might want to speed up cross-server queries by providing a local copy of the data. You might want to make the data available to resource intensive reporting queries without affecting the OLTP load, maybe even with an intentional delay in synchronization, so that reports run against complete days only. You may wish to replicate a complete database to a secondary 'standby' server for high availability.
