Business continuity is the ability of an organization to maintain the delivery of products or services at acceptable levels following a disruptive incident. These incidents can range from natural events such as fires and severe weather to mechanical or coding failures such as server crashes and programming bugs, as well as from malware and hacking events such as crypto viruses. Business continuity planning takes into consideration the level of acceptable downtime (RTO) and data loss against the costs associated with preventing data or production losses.
At its most basic level, organizations should implement basic disaster recovery capabilities into their systems. This includes redundant storage to mitigate disk failures as well as a robust data backup strategy to secure data.
Recovery time objectives (RTOs) can vary by organization, and those requiring lower RTOs should consider implementing server mirroring and clustering, moving their hardware to data centers, or migrating to a cloud computing platform that meets their redundancy and continuity needs.
