THE IMPORTANCE OF BLOG BACKUPS
So today I’m going to cover all the things you can (and should) have copies off.. just in case something goes terribly wrong.
There are 4 main parts to your blogspot blog that you should be backing up:
1. Your content. The HTML that makes up all of your posts and pages.
2. Your template. The code that packages up your content so nicely in your browser.
3. Your images. Contrary to popular belief, no, in fact your images are NOT backed up when you
back up your content. Your images are actually hosted outside of your content and so if you want to make sure they are never lost, you probably want to keep a copy of each and every one of them.
4. Your HTML gadgets. The content within your HTML gadgets (your sidebars and footers) floats in a strange “no mans land” when it comes to Blogspot. It isn’t backed up with your template, nor is it backed up with your content. Typically it wouldn’t be catastrophic to lose the little bit of HTML in your sidebars (usually it is images and text for things like buttons or ads or whatever you keep in your side bar). However, if you ever want to migrate to a new blog or new template, having a copy of those gadgets is a good idea.
