The maximum targeted period in which data might be lost from an IT service due to a major incident. Strategies include frequent backups and real-time replication.

The process of restoring operations to the primary system or original state after a failover. Strategies include careful monitoring and tested procedures for reversing failover.

An equipped data center that does not have customer data preloaded, but is available to receive data and begin operation within a few hours. Strategies include periodic updates and rehearsed transition processes.

Data replication occurs with a delay, meaning the backup copy is slightly behind the primary data. Strategy includes using it where some data lag can be tolerated to improve performance.

A documented, structured approach for handling potential disruptive events. Strategy includes well-defined steps for detection, communication, containment, and resolution.

A type of backup that only copies the data that has changed since the last backup. Strategy includes using it in combination with full backups to minimize data loss and speed up recovery.

The use of multiple cloud service providers to mitigate the risk of a single point of failure. Strategy includes diversifying providers and having interoperable cloud services.

Classification system for data centers based on redundancy and fault tolerance. Tiers range from I (least redundant) to IV (fully redundant). Strategy is to choose the appropriate tier for business needs.

A holistic management process that identifies potential threats to an organization and the impacts to business operations. Strategies include regular revisions and training exercises.

A facility that has all the required physical amenities but does not have the technology systems in place. Strategy includes keeping hardware agreements and quick installation processes.

A complete copy of an organization's data files and programs. Strategy includes performing these periodically to ensure a complete restore point.

A fully operational offsite data center with hardware and software, staff and customer data, ready to be used at a moment’s notice. Strategy is maintaining duplicate systems that are always running parallel to the primary site.

A procedure by which a system automatically transfers control to a duplicate backup system when it detects a failure. Strategies include using replication and load balancers.

The act of copying and maintaining database objects, data files etc. in more than one location. Strategies include real-time data replication and asynchronous/synchronous replication.

The targeted duration of time within which a business process must be restored after a disaster to avoid unacceptable consequences. Strategies include having redundant systems and automated failover.

A method of data replication where the data is written to both the primary and the backup location simultaneously. Strategy includes using it in systems requiring high availability and zero data loss.

The longest period of time that a system can be down after a disaster without causing irreparable damage to the business. Strategies to reduce MTD include proactive planning and having resilient systems.

Third-party cloud service that allows organizations to failover their physical or virtual servers to a cloud computing environment. Strategies include selecting a reliable DRaaS provider and ensuring proper setup.

A process that predicts the consequences of disruption of a business function and process and gathers information needed to develop recovery strategies. Critical to BCP.
