Amazon RDS for SQL Server now supports retaining CDC configurations when restoring database backups in Amazon Web Services China regions
Amazon Relational Database Service (Amazon RDS) for SQL Server now allows maintaining Change Data Capture (CDC) settings and metadata when restoring native database backups in the Amazon Web Services China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, operated by NWCD. CDC is a Microsoft SQL Server feature that customers can use to record insert, update, and delete operations occurring in a database table, and make these changes accessible to applications. When a database is restored from a backup, CDC configurations and data are not preserved by default, which can result in gaps in data capture. With this new feature, customers can preserve their database CDC settings when restoring a database backup to a new instance, or a different database name.
To retain CDC configurations, customers can specify the KEEP_CDC option when restoring a database backup. This option ensures that the CDC metadata and any captured change data are kept intact. Refer to the Amazon RDS for SQL Server User Guide to learn more about KEEP_CDC.
