@gich3 I don't think there's a way to download the snapshots (or even backups). I can't find a way.
So my recommendation is that you tar.gz your content (and config files) and then download it. At least, that's what I did.
Hope it helps!
@jpablois correct. There is not a way to download the ISO. since it's a cloud image, it's not really an ISO anyway, it's a vm image in some format. I think they use OpenStack images.
Best you can do is grab the web root, and conf files from apache. Don't forget SSL cert files if you need them too. but if you're moving servers, not a bad idea to rekey the SSLs.
