This concept can be applied automatically and continuously to create a high-availability solution called log shipping. With log shipping, a primary production database sends a transaction log backup to one or more secondary databases on secondary instances of SQL Server. These secondary databases are duplicate copies of the primary database and continually restore the transaction log backups to their own copy in order to keep it in sync with the primary database. Because the secondary database is on physically separate hardware, should the primary fail for any reason, a fully backed up copy of the system is immediately available and network traffic can simply be rerouted to the secondary server without end users ever…
