BACK UP YOUR CONTENT OF YOUR BLOG
(Pages, Posts, etc)

In the Design Mode of your Blogger -

 

Go to Settings - Other

Then you will see Import and Back up

Click on the Back up Content -

Save the file -

Now, if you ever lose your blog, you will have all the pages/posts
available as to the day you backed it up!!

It is a great idea to back up your content the same time you
back up your theme at least once a week or once a month!!
