Continuous Data Protection
Continuous Data Protection (CDP) is a data backup methodology that continuously captures and saves data changes in real-time or near-real-time, enabling recovery to any point in time. Unlike traditional backup methods that rely on scheduled snapshots, CDP tracks every write operation, providing granular recovery options and minimizing data loss. It is commonly implemented in storage systems, databases, and disaster recovery solutions to ensure high availability and data integrity.
Developers should learn and use CDP when building or maintaining systems that require minimal data loss and high recovery point objectives (RPO), such as financial applications, healthcare databases, or e-commerce platforms. It is particularly valuable in environments with frequent data updates, as it allows for precise rollback to specific moments, reducing downtime and ensuring compliance with data protection regulations. CDP is also essential for implementing robust disaster recovery strategies in cloud-native or hybrid infrastructures.
