Planning for DR
Planning for DR requires a balance of cost and time needed for a business to recover from an outage. The shorter the time expectation, the more expensive the DR solution.
It is important to understand two key SLAs for the business use case:
- Recovery Time Objective (RTO) refers to the duration in which a business is mandated to recover from an outage. For example, if RTO is 1 hour and it is 30 minutes since the outage, then we have 30 more minutes to recover and bring the operations back online without violating the RTO stipulations.
- Recovery Point Objective (RPO) refers to the maximum time period of a disruption after which the loss of data collection and processing will exceed the business's agreed-upon threshold. For example, if backup was done in the last hour and the defined RPO is 2 hours, we still have an hour to recover from the disruption to the business.
In the next section, we will see how to use these values of RTO and...
