CompTIA Cloud+ (CV0-004)OperationsEasy
A cloud administrator is tasked with implementing a disaster recovery strategy that ensures minimal data loss for a critical financial application. The application processes transactions continuously, and any data loss could result in significant financial penalties. Which of the following backup and restore strategies would best meet this requirement?
- AWeekly full backups with daily differential backups.
- BMonthly full backups stored offsite.
- CDaily full backups with weekly incremental backups.
- DContinuous data protection (CDP) with near-zero recovery point objective (RPO).
Show answer & explanationAnswer & explanation
Correct answer: D. Continuous data protection (CDP) with near-zero recovery point objective (RPO).
Continuous Data Protection (CDP) records every change to data, allowing recovery to any point in time, thereby achieving a near-zero Recovery Point Objective (RPO) and minimizing data loss for critical applications.
Why the other options are wrong
- A. Weekly full backups with daily differential backups would result in up to 24 hours of data loss from the last differential backup.
- B. Monthly full backups are highly insufficient for a critical financial application requiring minimal data loss; this would lead to significant data loss.
- C. Daily full backups with weekly incremental backups would still result in up to 24 hours of data loss.
Continuous Data Protection (CDP)
A backup and recovery strategy that continuously captures or tracks data changes, allowing recovery to any previous point in time with minimal data loss.
- Offers near-zero Recovery Point Objective (RPO).
- Captures changes as they occur, not just at scheduled intervals.
- Ideal for mission-critical applications where data loss is unacceptable.
Memory trick: CDP: Continuous Data Protection, Continuously Does Protection.
