If you use Content Exporter in Confluence Cloud, it will run on our own servers in the Cloud. We operate our Cloud add-ons using Amazon AWS services.
Data storage and location
Content Exporter does not store any personal data (such as names or e-mail addresses and so on).
As Content Exporter itself does not store relevant data, it does not need to be migrated between the Cloud and Server platforms. Simply install the latest version of Content Exporter in the target platform with a valid license key.
You can use this regex for example: "^content-export-.*$"
