如何检测时光机？

Question

我需要将用于时光机的硬盘分区与其他普通分区区分开来。是否有API检测时光机分区/卷？

Answer 1

只要你使用的是Lion或更高版本，苹果就为时光机添加了一个名为tmutil的命令行实用程序。根据手册页，运行tmutil destinationinfo将返回以下信息：

Name          The volume label as shown in Finder.
Kind          Whether the destination is locally attached storage or a network device.
URL           In the case of a network destination, the URL used for Time Machine 
              configuration.
Mount Point   If the volume is currently mounted, the path in the file system at which
              it was mounted.
ID            The unique identifier for the destination.

When the -X option is provided, output will be printed in XML property list format.
