I guess only a few people know about the Import/Export feature in Blogger. You can access it from the "Settings" tab of your Blogger dashboard. Here are 3 screenshots I made for you, to visualize the 3 steps to save your blog:
3 clicks and a little download time. That's all it takes to create a complete backup of your blog on your hard drive. This might safe your butt when you accidentally delete some older blog post, or if Google blocks your blog due to policy violations.
If you only want to save the "Look" of your blog, and don't care about your content being lost, you can go ahead and safe the template. This is easy as well:
- Choose "Template" in your Blogger Dashboard
- Click the "Backup" button in the top right corner
This will download the full template in XML format.
