Log shipping is the process of automating the backup of transaction log files on a primary (production) database server, and then restoring them onto a standby server. This technique is supported by Microsoft SQL Server, [1] 4D Server, [2] MySQL, [3] and PostgreSQL. [4] [5] Similar to replication, the primary purpose of log shipping is to ...
Terminology and overview.
