Re: Bit OT : diff bet'n business continuity and high availability

I agree with Niall. To put both things into more technical terms, I consider business continuity to typically refer to disaster recovery solutions. So, that would make the technical question more about differentiating between high availability and disaster recovery.
The age old example for Oracle DB has often been using clustering (failover or RAC) for high availability and data guard for disaster recovery. I'm not sure that really holds true these days since data guard can get a lot closer to what failover clusters provide with its automatic failover features.
I should also mention that many organizations would make the technical disaster recovery plan for databases just one piece of their business continuity plan. For example, I was at an organization's business continuity site recently where there were a sea of desktop computers and phones lined up on empty desks. No one works there...normally. However, if there's a disaster at their primary site (which is about 50 miles away), then all workers are directed to commute to the business continuity site so that they can keep working. The existence and maintenance of that site is part of their business continuity plan. Of course, the business continuity site also had a data center with systems equivalent to the critical systems in the primary site's data center.
