Oracle database S3 Management
Why use S3 for Imports/Exports?
Using S3 allows traffic to flow directly from the RDS instance (where the db runs) to S3 (where the data is stored) without needing to move through the GSA network. This allows data to move much faster and avoid taxing GSA bandwidth for heavy data migration efforts.
Setup
Submit a JSM ticket to get an S3 bucket created for the purpose of holding the database backups. An IAM role will also be created and attached to your db so that it can reach the bucket.
Import/Export data to/from S3
Follow the directions in https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/oracle-s3-integration.html#oracle-s3-integration.using to set up a data pump to/from S3.
