Best Practices for a Business Continuity Plan
Organizations of all sizes are finding it more important than ever to maintain access to critical applications and data when hardware or software failures occur, even in the event of a natural or man-made disaster. All too often, however, failures do occur, resulting in nonavailability of the applications when the computing system stops. Whatever the cause, every computing system is vulnerable to failing at some point, and a strong business continuity plan is crucial to any organization.
For those who have considered protection against computing failures, various solutions have been proposed. They range from various backup schemes, file replication and hard disk mirroring to more dynamic solutions that use fully redundant hardware systems running in lockstep to automatically failover a computing system. Those solutions that can dynamically restore the application are sometimes referred to as high availability solutions, where restoration time can be less than twelve hours in the event of a system failure. There are also continuous availability solutions that keep running even in the event of a catastrophic hardware failure. So how do you decide when to use a high availability solution or a continuous availability solution? And what will best meet your business needs?
