This article explains how to easily make AWS cross-region backups with 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 the ADVANCED Option from the main backup policy section, Simply, click on the checkbox and select your chosen AWS region(s) from the dropdown menu where you would like to save the additional backup copies.
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.
