之前在这篇blog中介绍过使用Azure Client az 来部署生成到网站. 使用az很方便，但是也有些缺点，例如会把整个网站全部重新上传一遍，速度慢不说，还浪费多次blob的操作。后来找到了另外一个工具rclone（下载、安装、文档，或使用各平台包管理器安装），它可以像rsync一样同步本地和远端文件，只更新变化过的文件。

使用起来也很简单， 首先新建一个远端配置rclone config，根据提示，输入名字，类型，account 或者 connection string。例如，我配置 azure-chen 这个名字（本地名称）对应 azure 上 chen 这个 blob 账号。然后就可以使用了：

这样，就可以把远端有，而本地没有到删除，而本地新增到也会复制到远端，减少了很多IO。

另外，还有两个GUI工具(for macOS)：

Rclone Browser 略微有点小问题， 并至今有2年没更新了，需要自己查issues解决。
