3. Make back-ups

Go to tools > Export > All content > Download Export File > Save

As premium member your website will be backed-up at WA hosting too. The only problem is that they do that once per 2-3 days. And when you have written some terrific posts in between, and then wreck your website, it is GONE. So please make it a habit to make a back-up everytime you have done some work on your website.

I have had contact with Kyle about what exactly the back-up is WA is making from your website. As a premium member, this is one of the advantages.

Kyle:

You don't need to back up anything at all, your websites are completely backed up here at WA and that is part of the service we offer here.
However
I do recommend writing your content in Google Docs first or even within Rapid Writer here at WA so you have two stored versions of your content, moreso in case your connection dies while you are creating the content within Wordpress.
