Event-driven transfers from Cloud Storage

Storage Transfer Service can listen to event notifications in Google Cloud to automatically transfer data that has been added or updated in a Cloud Storage bucket. Learn more about the benefits of event-driven transfers.

Event-driven transfers from Cloud Storage use Pub/Sub notifications to know when objects in the source bucket have been modified or added. Object deletions are not detected; deleting an object at the source does not delete the associated object in the destination bucket.

Event-driven transfers always use a Cloud Storage bucket as the destination.

Configure permissions

In addition to the permissions required for all transfer jobs, event-driven transfers require the Pub/Sub Subscriber role.

1. Find the name of the Storage Transfer Service service agent for your project:

   1. Go to the googleServiceAccounts.get reference page.

      An interactive panel opens, titled Try this method.

   2. In the panel, under Request parameters, enter your project ID. The project you specify here must be the project you're using to manage Storage Transfer Service, which might be different from the source bucket's project.

   3. Click Execute.

   Your service agent's email is returned as the value of accountEmail. Copy this value.

   The service agent's email uses the format project-PROJECT_NUMBER@storage-transfer-service.iam.gserviceaccount.com.
