log shipping to multiple-read servers
Log Shipping is a high availability feature of SQL Server where a database copy from a specific point in time is made available to a different server using full backups + scheduled transaction log backups delivered by an internal mechanism of SQL Server.
It's composed of some SQL jobs and some executables and is accessible by a wizard - right click a database -> Properties -> Transaction Log Shipping.

It's no new functionality of SQL Server (if I recall correctly it's at least from SQL 2000).
