A company's online transaction system processes high-value financial transactions and cannot afford significant data loss. The company wants to ensure that in the event of a system failure, they can recover the most recent transaction data with minimal loss. Which of the following recovery strategies is the BEST to meet the company's requirement?
An RPO of zero, with real-time replication to a secondary site.
Increasing the frequency of the backup every 30 minutes.
A Recovery Point Objective (RPO) of zero means that the system is designed with high availability and fault tolerance in mind, ensuring that no transaction data is lost in the event of a system failure. This implies the use of real-time replication techniques, making it the most suitable option for the company's high-value transaction system. An RPO of 1 hour would mean accepting up to one hour of data loss, which isn't ideal for the high-value transactions. An RPO of 24 hours would suggest a much larger potential data loss window, which is not acceptable for this scenario. Lastly, increasing backup frequency could help reduce the amount of data lost, but it is not as effective as aiming for an RPO of zero, where data loss is nonexistent.
