> When the system began having problems Tuesday night, technicians switched to a backup. But because the backup was attempting to access the same damaged data, it also didn’t work, the person said. That's not a backup. Sounds like they have standby hardware for one tier of the architecture which they switched to, but since it wasn't a hardware failure it didn't change anything. One hopes they review not only their processes which allowed (one assumes) a configuration change to be applied without being verified, but also their backup strategy...
