You can use the below command to automate native backup of all the databases using msdb.dbo.rds_backup_database Stored procedure. You can also use the below script to schedule as a agent job to take native backup (in .bak file) of your all databases.

exec msdb..rds_task_status @task_id= 5 -- 5 as an example of your task id
