Our blog runs on Posterous, and for the most part I absolutely love it. But following on from a Tweet this morning by Christian Payne (from Documental.ly) I wondered how I would go about backing up our blog.

Turns out there's two options, neither of which I can get to download images, but that work well for downloading the text.

The first is by far the easiest and will work whatever system you're running on; http://www.backuperous.com/

This will produce an XML. Doesn't look pretty but it has all your text in there.

If you're on a Mac and have got a couple of minutes to spare then using Automator does a much better job.

Open up Automator and from the Internet selection drag ' Get Specified URLs', 'Get Linked URLs from Webpages ' and 'Download URLs' into the workflow window. Put your site address into the first section, make sure 'Only return URLs in the same domain' is ticked and start your workflow. Even easier you can download this file, open it up, put your site address in and you should be ready to go.

This workflow will then create separate files for each of your blog posts.

If you find an easier way to do any of this then please let me know!
