This white paper will provide a review of the core causes and costs of both planned and unplanned downtime and will then provide a detailed discussion of current options for High Availability and Disaster Recovery solutions.

It is a fortunate change of events for smaller companies that the powerful business continuity technology of high availability is no longer reserved for the largest enterprises. Because of dropping hardware and communications costs, the decreased cost of HA software, and a host of self-healing and self managing capabilities making HA simple to run, plus new options to purchase HA as a cost-per-month service, thousands of companies that used to precariously rely on tape backups as their sole disaster recovery strategy can now easily acquire more robust, full featured HA and DR protection, for far less than ever before.
