This will create a firestore backup every day at 6am, using the service account stored as a base64 encoded string secret named FIREBASE_BACKUP_GCLOUD_AUTH. The firestore is run in the project firestore-backup-test, the backup will be found in the Cloud Storage bucket gs://firestore-backup-test-backups. Only the collections users and admins will be included in this backup.

• gcloudAuth: base64 encoded service account- ideally stored as a secret in your repository
• 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.
