A log shipping session involves the following steps:
• Backing up the transaction log file on the primary SQL Server instance
• Copying the transaction log backup file across the network to one or more secondary SQL Server instances
• Restoring the transaction log backup file on the secondary SQL Server instances
Implementation examples
One of the common log shipping scenarios is the environment with two servers (SQLServer-1 – primary and SQLServer-2 – secondary), two SQL Server instances (SQLInstance-1 and SQLInstance-2), and one SQL Server database named SQLDB-1 with log shipping running on it
