Due to globalization, Web-based sales and service, more-vigorous competition, and more-stringent regulations, the goal of ensuring the availability and recoverability of data and applications has risen considerably on the priority lists of today's CIOs. A wide range of technologies is available to address this goal. At the apex of a spectrum of solutions sits a strategy that maintains highly redundant, geographically dispersed systems and data, commonly identified as high availability (HA) or disaster recovery (DR). Occupying the lower extreme is traditional tape-based backup, which provides reliable but rudimentary disaster recovery capabilities. But between the two sits a variety of technologies offering various levels of system availability and recovery speed and completeness.
