homepage Forums Air Combat & Civil Aviation EECH / EEAH wiki spam

I have little problem understanding the technical details behind such a backup.
Is this something totally independent of SimHQ and the internet connection to their website?
To put it in another way: if for any reason SimHQ goes offline will one be able to see the entire content of the wiki (text and pictures, etc.)? I realise that perhaps some legalities are involved, maybe?

@Javelin
HTTRack worked great for me too but I see all pictures are still hyperlinked to SimHQ. Thank you for the HTTrack suggestion.
And are those 2 wiki articles you posted some time ago: Advanced Topics and More AT available on wiki?
