Service-interrupting events can happen at any time. Your network could have an outage, your latest application push might introduce a critical bug, or—in rare cases—you might even have to contend with a natural disaster. When things go awry, it's important to have a robust, targeted, and well-tested. This article discusses general principles for designing and testing a disaster recovery plan with. Note: This paper discusses general principles of disaster recovery planning on Google Cloud Platform, walking you through the most relevant products and features. For a discussion of specific disaster recovery use cases, with example implementations on Google Cloud Platform, see the. Basics of disaster recovery planning As a subset of, disaster recovery planning begins with a business impact analysis. The idea behind this analysis is to work out two key metrics: • A, which is the maximum acceptable length of time that your application can be offline. This value is usually defined as part of a larger. • A, which is the maximum acceptable length of time during which data might be lost from your application due to a major incident. This metric will vary based on the ways that the data is used; for example, frequently modified user data could have an RPO of just a few minutes, whereas less critical, infrequently modified data could have an RPO of several hours. Note that this metric describes the length of time only; it does not address the amount or quality of the data lost. Taken together, these metrics have a roughly asymptotic impact on your bottom line. Typically, the smaller your RTO and RPO values are, the more your application will cost to run: Figure 1: Ratio of cost to RTO/RPO Because smaller RTO and RPO values often come with an increase in complexity, the associated administrative overhead follows a similar curve.
