Disaster Recovery / Business Continuity 

by Bethany Hendricks on Glossary • September 23, 2020

Disaster recovery is the restoration of computer systems including hardware, software and data to an operational state following a disruptive event.
It is important to have defined disaster recovery strategies in order to ensure operational and business continuity. These are documented in a business continuity plan and should also cater for situations whereby personnel key for operating business critical systems become unexpectedly unavailable.

A key strategy for disaster recovery that concerns hardware, software or data is having failover and redundant systems in place to ensure that critical business operations continue even after catastrophic failure within a business' IT infrastructure.
