An organization relies on a cloud provider for its primary data storage. To ensure business continuity and disaster recovery, they implement a strategy where data is continuously copied to a geographically distant data center, maintained by the same cloud provider, with a recovery point objective (RPO) of minutes. Which data protection strategy is being employed?
- AData Archiving
- BData Replication
- CData Backup
- DData Retention
Show answer & explanationAnswer & explanation
Correct answer: B. Data Replication
Data replication involves continuously copying data to another location to maintain a near real-time duplicate, which is essential for achieving a low RPO and supporting disaster recovery and business continuity.
Why the other options are wrong
- A. Data archiving is for long-term storage of inactive data, not for rapid recovery with a low RPO.
- C. Data backup creates point-in-time copies, which typically results in a higher RPO than 'minutes'.
- D. Data retention defines how long data must be kept, not the method of continuous data copying for disaster recovery.
Data Replication
The process of continuously copying data from one location to another, maintaining an up-to-date duplicate, primarily for disaster recovery, high availability, and load balancing.
- Continuous data copying.
- Aims for low RPO (Recovery Point Objective).
- Supports disaster recovery and business continuity.
- Can be synchronous or asynchronous.
Memory trick: Replication is like having a twin, always up-to-date and ready.
