The fact that blogger has been slow, and sometimes stopped, over the past couple of days – I’d have to guess due to a surge of post-election feeling – has made me (somewhat belatedly I admit) think about backups. I note from my profile that I’m past the 25,000 words mark, and the blog now contains lots of research that it would be a real pain to replicate. Does anyone know of a simple, easy way of backing up a blog on to a CD, or into a file that you could post to yourself, or similar?
TIA
