ICE Mirror

冰镜会比较镜像目录的主目录，并纠正任何差异。 ICE镜允许超高速的镜像，因为它执行的增量更新。换句话说，它仅复制已更改的文件。如果只有少数文件已更新，它执行速度非常快。

ICE Mirror will compare the mirrored directory to the master directory and correct any disparities. ICE Mirror allows ultra fast mirroring because it performs incremental updates. In other words it only copies files that have changed. If only a few files have been updated, it performs very fast.
