Here's a little quick and dirty post on backing up your blog on Blogger since every howto that I have seen online is a bit dated and things have moved. But that's to be expected, things are always moving when it comes to Google. Like all things in IT, you should make a regular backup of your blog just in case you have an oopsie, or Google determines you have violated their terms and shuts you down.
In your Blogger control panel, go into the settings for the blog you want to back up. On the left side of the page, you'll see Settings at the bottom of the list of categories. Click on Settings, then at the bottom of the Settings submenu, you'll see Other. Click on Other, and at the top of the page you'll see "Import & back up." Click the button labeled "Back up Content," and you'll be presented a save as dialog box which will let you save a single .xml file with all of your blog's settings and posts. If you examine the outputted .xml file, you'll find everything there. Should you wish to move your site do a different platform in the future, many platforms will be able to import this .xml file directly.
