Romania is not very digitalized, and it still has a lot of paper bureaucracy.

Even if the digital records were completely lost, they still have the paper ones.

> being unable to prove land ownership

People know who owns what, there are also paper contracts of ownership which are more authoritative than the digital records.

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.
