Exporter

If you're looking for a convenient way to make a backup of your WordPress blog, then the Exporter add-on is perfect for you. This add-on allows you to save your blog in WXR (WordPress eXtended Rss) format, which makes it easy to move your blog to other platforms like Blogfa or PersianBlog.

One of the standout features of this add-on is its use of DOM to parse your weblog pages. This allows the add-on to store your pages in XML format with WXR format on your desktop. Those with knowledge of DOM can even add new systems to this functionality, expanding the add-on's usefulness even further.

The Exporter add-on is compatible with all major operating systems, including Mac OS X, Windows, and Linux. This cross-platform functionality ensures that no matter what computer you're using to access your blog, you can always back it up and move it to new platforms as needed.

Overall, if you're looking for a reliable and convenient way to make backups of your blog, then the Exporter add-on is an excellent choice. Its use of WXR format and DOM functionality make it a powerful tool for users of all levels of technical expertise.
