AWS is ideally suited for making the user’s applications tolerant to disaster. One of the options for making the user’s application suitable to DR is to keep a back up of the data / application setup in multiple regions. If the first region is not reachable due to some reason, the user can start the application from the other region. In Dec, 2021 AWS introduced functionality to copy snapshot across regions.
This guide demonstrates how to copy a snapshot of a Linux based instance to another region as well as attach a volume to a new instance to complete the instance data migration across regions.
