Which of the following should be the PRIMARY consideration when designing a backup strategy for an online reservation system that requires high availability?
The primary consideration when designing a backup strategy for an online reservation system that requires high availability is the Recovery Time Objective (RTO). RTO represents the maximum acceptable amount of time that a system can be offline. For an online reservation system, high availability is critical, meaning it needs to be back online quickly after any disruption. Therefore, designing a backup strategy that minimizes downtime and meets the required RTO is essential to ensure continuous operation and minimal impact on users.
RTO indicates the maximum time allowed for a system to recover from a failure. For systems that require high availability, quick recovery is important, so it is most important to clearly define the RTO and design a backup strategy based on it. Although RPO is also important, RTO tends to take priority, especially in situations where availability is important.
