By default, Amazon Redshift has excellent tools to back up your cluster via snapshot to Amazon Simple Storage Service (Amazon S3). These snapshots can be restored in any AZ in that region or transferred automatically to other regions for disaster recovery. Amazon Redshift can even prioritize data being restored from Amazon S3 based on the queries running against a cluster that is still being restored.
