ComputerWeekly – Disaster recovery testing: technology systems to test DR

In this concluding part of a two-part series, Computer Weekly looks at ways of testing disaster recovery (DR). In the first article, we discussed the need for disaster recovery and for developing a strategy to test the backup process.

We discussed four main items that need to be evaluated to ensure successful testing. These were:

Time – Evaluating the time since a test was last performed and measuring the time to complete recovery, from a RTO (recovery time objective) perspective.
Change – Testing after major changes occur in the infrastructure, such as application upgrades or infrastructure (hypervisor changes).
Impact – What is the impact of running a test? Can a test be run without impacting the production environment?
People – How do we consider the human factor from the perspective of taking human error out of the recovery process?

In a virtual environment, the options for recovery can be divided into four main sections.
