Reconstructing that archive from the records would be close to impossible. The documents they issue and banks/notaries and others have have 30 day expires. In theory most of these documents are issued on sale / mortgages / loans against these type of assets. Both notaries and banks have their own record system - I don't think there's a common system they all use, for notaries I'm not sure if they keep electronic records of these papers .. the system that was hacked was supposed to be it.
