Log shipping transfers database dumps and logs from the primary server to the secondary server. As with any warm standby solution failure detection and failover processing is not automated. When log shipping is employed the standby database cannot be used for data access. The standby database is unavailable throughout the continual process of loading database and transaction log dumps from the primary server. Because log shipping transfers complete database logs all logged schema and data changes are transferred from the primary to secondary node. When log shipping is employed it is not possible to partition the data or transfer only a subset of the objects from the database.Use replication when you want a warm standby solution and when simultaneous data access on the secondary node (scale out for read) or object or data partitioning is a requirement.
