For example, if you set the PreferredBackupPeriod parameter to Saturday,Sunday and the BackupInterval parameter to -1, a snapshot backup is performed on every Saturday and Sunday.If the instance runs PostgreSQL, the BackupInterval parameter is supported only when the instance is equipped with standard SSDs or enhanced SSDs (ESSDs).This parameter takes effect only when you set the BackupPolicyMode parameter to DataBackupPolicy.

This parameter takes effect only when BackupMethod is set to Physical. If BackupMethod is set to Snapshot, backups are forcefully performed on the primary instance that runs SQL Server on RDS Cluster Edition.
enable_increment_data_backup - (Optional, Bool, Available since v1.229.1) Specifies whether to enable incremental backup. Valid values:

log_backup_local_retention_number - (Optional, Int, Available since v1.229.1) The number of binary log files that you want to retain on the instance. Default value: 60. Valid values: 6 to 100. ->NOTE: This parameter takes effect only when you set the BackupPolicyMode parameter to LogBackupPolicy. If the instance runs MySQL, you can set this parameter to -1. The value -1 specifies that an unlimited number of binary log files can be retained on the instance.
backup_method - (Optional, Available since v1.229.1) The backup method of the instance. Valid values:
- Physical: physical backup
- Snapshot: snapshot backup ->NOTE: This parameter takes effect only on instances that run SQL Server with cloud disks. This parameter takes effect only when BackupPolicyMode is set to DataBackupPolicy.

-> NOTE: Currently, the SQLServer instance does not support to modify log_backup_retention_period.

Attributes Reference

The following attributes are exported:

id - The current backup policy resource ID. It is same as 'instance_id'.

Import

RDS backup policy can be imported using the id or instance id, e.g.
