Architecture

Bacula Enterprise Google Workspace Plugin is using several Google Workspace APIs to perform almost all of its operations. Therefore, the plugin is working at the maximum granularity that the service provides.

Google Workspace APIs

All the information is gotten using HTTP requests to Google Cloud from the FD where the plugin is installed.

The plugin will contact a Google Cloud Platform application that needs to be manually created and configured before using the plugin. It will serve as a bridge to download the required data or objects during backup time and send them to the Storage Daemon. Conversely, the plugin will receive them from an SD and perform uploads as needed during a restore operation.

The implementation is done through a Java Daemon, therefore Java is a requirement in the FD host. For more information about how to create the application in GCP, please, consult Authorization section.

Below is a simplified vision of the architecture of this plugin inside a generic Bacula Enterprise deployment:
