Automated Cross-Region Snapshot Copy for Amazon Redshift
As part of our plan to make it even easier for you to build and run AWS applications that have a global footprint, I am happy to announce that Amazon Redshift now has the ability to automatically back up your cluster to a second AWS region!

Once you enable this feature, Redshift will make subsequent snapshots available in the second region.
