在一年多之前，我写过一个博客介绍Fabric（Fabric 一个与多台服务器远程交互的Python库和工具），前段时间我也在项目中也大量使用了Fabric来管理很多服务器。
我的博客搭建在一个KVM VPS上，今天也写了一个fabfile来dump数据库、打包WordPress目录，并下载到本地。fabfile代码如下：

当然，我一般也会使用BackWPup插件来备份WordPress；刚好发现，前段时间使用Nginx替代Apache后，BackWPup运行时仍然要写“/var/www/html/wp-content/backwpup-logs/”目录，所以有个权限问题，最近两个月都是运行失败了。后来对这个目录开放了写权限就没问题了。
