In an enterprise environment, which of the following

Solution

Incremental Backup offers the best balance between minimizing storage usage and meeting a specific Recovery Point Objective (RPO). An incremental backup only saves the changes made since the last backup (whether full or incremental), reducing the amount of storage required. This strategy allows for faster backups while ensuring that data can be recovered efficiently to a recent state. While incremental backups require all previous increments for a full restore, modern backup management systems mitigate this complexity with streamlined recovery processes, providing a good trade-off between efficiency and recovery needs. Why Other Options are Incorrect: A) Full Backup: Full backups are the safest but consume the most storage and time, making them less efficient for frequent backup needs. C) Differential Backup: Differential backups save all changes since the last full backup, leading to increased storage usage over time compared to incremental backups. D) Continuous Data Protection (CDP): CDP captures every change in real-time, which is ideal for near-zero RPO but comes with significant storage and resource overhead. E) Snapshot Backup: Snapshots are useful for point-in-time recovery but do not provide as granular data recovery options as incremental backups.
