Johnston reported this year's experience of one firm that consulted with him after it had a disaster that took it offline. "This firm had a catastrophic failure on March 13," he said. "The backup system was recording that the backup was occuring, but nothing was getting backed up."
Speaking at a session about disaster recovery and planning at the recent CCH Connections user conference, Johnston warned that if backup systems have not been installed correctly, they will report that backups are being performed as desired even if they aren't. So users have to go beyond the basics.
"It has to be tested on a pretty regular basis," he cautioned.
Johnston, a partner with the Network Management Group, also devoted a significant amount of his talk to the threat of CryptoWall computer infections. These are the attacks in which an outsider uses code to lock up a computer and demand a ransom from the owner in order to free up the device.
He reported hearing about two or three of these a week. And where those holding the computer hostage were once demanding between $350 and $500 to free the system, that has generally escalated to $1,500 to $3,500 for each ransom demand.
