Only the collections users and admins will be included in this backup.

• projectId: Your gcloud project id
• storageBucket: Gcloud Storage bucket to hold our backup
• collectionIds: Optional comma-separated list of collections to be included in the backup. If not specified, all collections will be backed up.
