Continuous Backup
Continuous Backup is a data protection strategy where backups are created and updated in real-time or near-real-time as data changes, rather than on a scheduled basis. It ensures that the most recent version of data is always available for recovery, minimizing data loss in case of failures, corruption, or disasters. This approach is often implemented using technologies that capture and replicate incremental changes to backup storage systems.
Developers should learn and use Continuous Backup in scenarios where data availability and minimal recovery point objectives (RPO) are critical, such as in financial systems, e-commerce platforms, or healthcare applications. It is essential for reducing downtime and data loss during incidents like server crashes, ransomware attacks, or accidental deletions, providing a robust disaster recovery solution.
