That’s why you backs ups and redundancy.
Data backups aren’t the issue here.
The dealers are trying to process NEW transactions, but they can’t because they system is down.
And it turns out that this is more than just no processing of new car sales, used car sales, leases, maintenance, repairs, warranty work.
Also, the connection to the software on the car so the dealer can diagnose and update - that’s also down in many cases.
