What is Log Shipping?
Log shipping is the method of automating the backup of database and transaction log files on a production SQL server, and then restoring them onto a standby server. Enterprise Editions only supports log shipping. In log shipping the transactional log file from single server is automatically updated into the backup database on the other server.
