Applications and services to include in a DR test
Only a limited number of services and applications can be realistically included in a DR
test plan. Consider your customer's criticality of services, exposure
to loss, risk tolerance,
and threats and vulnerabilities assessments to determine what needs to be included. This will also
help you prioritize which services must be restored and in what timeframe, based on recovery time
objectives (RTOs) and recovery point objectives (RPOs).
Don't neglect low-priority services that high-priority apps depend on in a DR test. With IT
services and infrastructure tightly intertwined, it's pertinent to consider and exercise all
aspects that impact the recovery of mission-critical services, including the following areas:
- The network
- The data center
- Communication systems

recovery: Test, test and test some more.
