	 * cause only the first entry in the options array to be used.
	 *
	 * - config_templates : not implemented yet: indicates that
	 * the remote storage module can output its configuration in
	 * Handlebars format via the get_configuration_template() method.
	 *
	 * - conditional_logic : indicates that the remote storage module
	 * can handle predefined logics regarding how backups should be
	 * sent to the remote storage

	 * mentioned are assumed to not be supported)
