Offline backups and parallel systems are becoming essential for business systems. Eugene Kaspersky (pictured), CEO of Kaspersky Lab, told channel partners recently that they should be urging businesses to back up sensitive data. The threat was highlighted last year by the Shamoon attack on Saudi Aramco, which used malware that wiped out the company's data. Individuals should also back up data on laptops and mobile devices. The rule of thumb from most security experts is to keep three copies of important files. In addition to being stored on the device itself, security experts advise backing up the data on a physical drive in a secure location and in a secure cloud environment you trust.
