原始的存储库和其副本均包含同样的数据地图对象，这是因为数据地图是不能修改的，这一点在本文稍后的部分介绍。
These copies, however, contain the same data map objects as the original repository, which is OK because data maps are not modified after being created and populated with the form data.
这些副本都包含与原始存储库相同的数据地图对象，这一点没错，因为数据地图在用表单数据创建和填充之后不会被修改。
Instead of a map to the original data, there are now new blocks with data, consuming disk space in the file system.
没有对原始数据的映射，现在只有新的数据块在消耗文件系统中的磁盘空间。
