For storing the backup file you need to create a bucket in S3 storage. Navigate to S3 storage and add the bucket as shown below

Keep the default settings as it is. Once you are ready with the bucket, All you need to do is to execute the below command on your MMC

exec msdb.dbo.rds_backup_database

@source_db_name=’database_name’,

@s3_arn_to_backup_to=’arn:aws:s3:::bucket_name/file_name.extension’
