A Business Continuity Plan identifies a business’ vulnerability to both internal and external threats and manufactures soft and hard assets that offer efficient prevention and recovery for the business.

At the same time, it retains value system integrity and competitive advantage. The plan is a framework for continual operations under adverse circumstances such as crime or disaster.The database design phase identifies the most lucrative disaster recovery solution which meets the data requirements and minimum applications and time in which both must be accessible.

It comprehensively specifies the actions a business should take before, during and after the disaster Disaster recovery plans take place as a compartment of defining the steps undertaken in business continuity planning.

The physical and logical units in an IT environment that necessitate the application of business continuity procedures include internal and external disk storage, microcode and firmware, disk partitions and networking design. The database design principles employed in disaster recovery entail: creating baseline specifications for primary systems e.g. PBX system and secondary systems like call centre or voicemail, determining how and if the system would interfere with the existing systems, establishing who will be using the system and whether network assets are necessary, determining database security, change control requirements (Blokdija et al, 2008).

Managers unwilling or late to invest in these technologies will incur losses as competitors will execute a greater volume of operational duties like backup at their regional facilities.

A considerable part of the business continuity process cannot be sourced from outside the business. Outsourcing can be cost effective as the cost of equipment is shared. Managers sometimes face problems outsourcing due to lack of local resources to support the recovery.
