Business continuity plans ensure people have a place to work when their original location becomes unusable. A BC plan should outline essential business functions, clearly identify those systems and processes that must operate without interruption, and specify how to maintain them. It should take into account any possible business disruption.
A DR plan is a broad term that describes a process to recover disrupted IT systems, networks and other critical assets an organization uses. Having a DR site is a crucial factor when planning your organization’s recovery from any disaster.
Companies can set up an internal site that it owns and manages, or an external site through a cloud or service provider. Organizations that need data back quickly often choose an internal site, typically a second data center that enables quick resumption of business. However, cloud-based disaster recovery options increasingly offer fast response times to meet tight recovery time objectives.
