The purpose of the BackWPup WordPress plugin is simple: backup your entire WordPress blog. There are many plugins available that can accomplish the goal of backing up your WordPress blog, but to me, BackWPup does things better than most other backup plugins.
I am an advocate of regularly backing up data on my local computer and this same train of thought has also transferred over to managing my blog. I have read many stories of people losing their blog because something bad happened and they don’t have a backup to restore their blog’s data. BackWPup provides you with all the options needed to completely backup your blog automatically.
