An effective business disaster recovery plan is like building or travel insurance - you don't realise how important it is until adversity strikes.
Unexpected events that disrupt normal business activity can have a major impact on operations, staff and customers. Having in place a comprehensive plan to deal with such events is a vital part of effective management.
When it comes to their IT systems, many large companies tackle disaster recovery (DR) by establishing an offsite facility that can support business systems should a catastrophe strike. Critical applications and data is replicated in this facility and kept in a state of readiness at all times.
Smaller companies, however, often find they cannot readily afford such an approach. The overheads associated with purchasing and maintaining duplicate hardware and applications that may never be used make it a very expensive option. Add the extra IT management requirements and this approach to DR moves even further out of reach.
