Jon William Toigo presents step-by-step coverage of disaster recovery techniques that reflect the latest technologies in data storage, networks, server systems, and the Internet. Toigo presents focused, hands-on coverage of the disaster recovery issues that matter most to your organization, including Web, e-commerce, and ERP/supply chain disaster recovery; low-cost steps you can take right now to dramatically reduce your risks; and much more. This edition's extensive new coverage includes new data storage topologies, data re-hosting issues, protecting against ongoing power outages such as those recently faced in California; new mailroom procedures; new physical access controls; and much more.
