Online Backup for WordPress allows you to easily backup your WordPress site with encryption locally, to email, or free 100 MB secure online storage.
I recently gave this plugin a one star review because I thought it would help me restore my site, too. This plugin doesn't do that. This is one of those plugins that you have to spend some time with (20-60 minutes) to use properly, so if you are looking for something simple, I would not recommend this.
I should note that the developer was very friendly and helpful with my problem, but I have since moved on to an easier to use plugin that does what I want.
