A business continuity plan is sometimes referred to as a disaster recovery plan because it allows for the preservation of critical data and other elements of your business.

You must make sure that your customers’ data is safe and secure and it usually involves putting it in a remote location or a SkyDrive outside of your location in which the disaster occurred.
