People write blog's for all kinds of reasons and there can be nothing more heartbreaking than to try and open your blog and find it has disappeared!
I am trying to get into the habit of downloading my blog template, blog posts and photographs, once a month. That way, should anything happen, I will hopefully have a copy to upload or at least keep as memoirs. This is not difficult to do but it does take time.
Login into your account. When I log in, my dashboard opens but you may have to get to yours. Find and open up your dashboard, then follow these instructions. Sorry for the slightly fuzzy appearance but this is a tidied up screen shot and helps save room in my Picasa album!
I have a folder on the desktop of my computer called "Blog Backup" where I store all these downloads. When I save next month, I make sure they are put into this folder, before I delete the old ones!
