Dell EMC Data Domain is a disk-based backup and recovery solution that incorporates inherent source-based deduplication technology. This deduplication reduces the amount of data that needs to be stored by eliminating duplicate copies of repeating data, thus improving storage efficiency and reducing costs. Data Domain systems are designed to provide reliable and high-performance backup and recovery services.References: Dell Information Storage and Management V5, Backup and Recovery Solutions,Dell Certification Resource

A software-defined data center (SDDC) is an architecture that extends virtualization concepts such as abstraction, pooling, and automation to all of the data center's resources and services. In an SDDC, IT resource components like computing, networking, storage, and security are all virtualized, except for the commodity hardware used to create resource pools. This virtualized environment enables more efficient resource management and scalability.

Continuous Data Protection (CDP) is a data protection method that continuously captures or tracks data modifications and stores changes independently of the primary data. A CDP appliance works by intercepting all writes to the production volume. It splits each write operation into two copies: one copy is written to the production volume, and the other is sent to a separate storage location where the changes are logged. This enables recovery to any point in time and helps ensure data integrity.
