This article explains how to easily make AWS cross-region backups with Druva CloudRanger.
Copy your backups to additional AWS regions
A backup policy will automatically generate a backup in the origin AWS region. If you would like to save an extra copy to another AWS region(s), we provide the functionality to do this in up to two additional AWS regions.
When you choose to create or edit a backup policy from the main backup policy page, simply select the Save extra copies to other regions checkbox and select the preferred AWS regions to save the additional backup copy. This will then save the additional copies in your chosen region(s) and the retention of these snapshots or AMIs in your additional region(s) will be the same as outlined in your backup policy.
