Before we get into some nitty gritty blogging tips and techniques, there are a few things you should understand. If you have a blog on a free service like Blogger, you will not be able to see these pieces but they are there.
1. The first piece is a database. A database contains the actual text that is displayed on your blog. It also contains settings and preferences as well. The database is the heart of your blog.
2. The second piece is the application files. These are the files that make stuff happen when you click the Post button. They are the files written in a coding language that pull the text from the database and display it. The application files are the brain of your blog.
3. The third piece is the theme. The theme files are generally thrown in with the application files, but I feel they are important enough to be their own piece. The theme can and should be customized to fit your personality or to beautify your blog. The theme controls the colors, how many columns of text you have, what photo is displayed in the header among many other little details. The theme is the skin of your blog.
The main reason I’m explaining these pieces to you is so you will understand when I say backups are very important — but only if you backup the correct files. If you’ve been blogging more than a week, you have an idea how long it takes you to write a post. If you’re blog disappeared, you’d probably be pretty sad that what you’ve written evaporated into internet space.
Backing up the database is one of the most important things you can do for your blog. It is, after all, the heart of your blog. Without it, your blog dies. The theme is also important to backup as you will have most likely customized parts of it. The application files can always be replaced. For example if you are running WordPress and one of those files got messed up, you could just download WordPress again from the main site (assuming the versions are the same!).

If you are running your own hosted version of WordPress, I highly recommend you install the WP-DBManager Plugin. You’ll be able to setup automatic backups to be emailed to you or stored on your server.
