Setting a Cross-Region Backup Policy

Function

This API is used to set a cross-region backup policy in the source backup region.

• Before calling an API, you need to understand the API in Authentication.

Constraints

• If the cross-region backup policy has been enabled, call the API to set the cross-region backup policy. Only the retention period can be changed.
• For RDS for MySQL and RDS for PostgreSQL DB instances, the retention period of automated full backups must be the same as that for automated incremental backups.
• For RDS for MySQL and RDS for PostgreSQL DB instances, automated incremental backup cannot be enabled unless automated full backup is enabled first.
• For RDS for MySQL and RDS for PostgreSQL DB instances, if you want to disable automated full backup and automated incremental backup, disable automated incremental backup first.
• Cross-region backup is not supported for RDS for MySQL or RDS for PostgreSQL instances with volume snapshot backup enabled.
