Which of the following terms refers to a storage technology that is used to capture real-time data changes and facilitate data restore points and recovery?
Continuous Data Protection (CDP) is a technology that continuously captures and saves data changes in real time or near real time, allowing for granular restore points. Unlike traditional backups that occur at scheduled intervals, CDP tracks every change to data, enabling recovery to any point in time before a failure. In this context, CDP is the best fit as it facilitates real-time data capture and recovery.
Option B (Mirroring):Mirroring duplicates data across two or more storage devices for redundancy but doesn’t inherently capture real-time changes for multiple restore points.
Option C (Virtual Tape Library):A VTL emulates tape storage using disk-based systems, primarily for backup, not real-time change capture.
Option D (Disk-to-Disk):D2D refers to backing up data from one disk to another, typically at scheduled intervals, not in real time.
EDRP v3 discusses CDP as an advanced backup technology under data protection strategies, highlighting its role in minimizing data loss by providing continuous recovery points (Module: Data Backup and Recovery).
