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.
If single server fails, the other server will have the similar db and can be used this as the Disaster Recovery plan. The key feature of log shipping is that it will automatically backup transaction logs throughout the day and automatically restore them on the standby server at explained interval.
