The capability of remaining or returning to a normal situation after an event by having multiple ways of performing a function. This may include people, processes or technology. Generally speaking, this means there would be no single point of failure that could stop a process.
The period of time following an event within which a service or activity must be resumed or a technology resource recovered.
The point in time, prior to a disruption or outage, to which essential data can be recovered after an outage. This defines the maximum level of data loss that is acceptable in the event of an outage or incident.
Restarting technology operations after an outage using processes, policies and procedures prepared for recovery or continuation of mission-essential technology infrastructure after a disaster.
These processes are found in a DR Plan. DR is a subset of business continuity and COOP.
The three principal goals of DR are to:
Save data,
Save hardware, software and facilities
Resume critical processes/restore data.
The effort to ensure that mission-essential functions continue to be performed during a wide range of emergencies which could be localized or widespread.
