it took months to go back fully online. they also had usable backups (so they used those for the data), but the infrastructure had so many vulnerabilities that they had to fix it first, hence the delay
Property is not fluid and doesn't change hands very often. Sure, in a large enough market lots of activity happens every day, but any given property is only involved in a transaction once a decade. You can have very old backups and still capture the state of the market to 99%+. Any recent activity will have brokers, buyers, and sellers, who all have current copies of their activity.
Also, this sort of event should result in some hackers being found and jailed for life as well as their families being bankrupted permanently. Or, if they are being protected by their government, this should be considered an act of war and an appropriate military response should be delivered.

Restored from very old backups and paper documents.
"Very old" could mean that they were not up to date. What did they do when the backups didn't match the actual situation at the time of the breach?
You do a comparison with the up to date papers. It just takes ages.
The involved parties and the notaries keep copies of every transaction.
