Backing up emails
 

Okay, so my computer is acting up. Can't access the internet at all, and then what good is a computer, eh?
Anyways, I've figured that now would be a good time to wipe the slate clean, so to speak, and delete everything on it. I hope it'll help.
Now, the thing is I have several email (around 2000) I'd like to back up, and 'put back' when I've finished deleting and installing software yet again.
Does anyone know where emails are 'saved' or how I could back them up?

Google.
