Backup and Recovery
Backup and recovery is a fundamental IT concept involving the creation of copies of data (backup) and the process of restoring that data after loss or corruption (recovery). It ensures business continuity by protecting against data loss from hardware failures, human errors, cyberattacks, or disasters. This includes strategies like full, incremental, and differential backups, along with recovery point objectives (RPO) and recovery time objectives (RTO).
Developers should learn backup and recovery to safeguard application data, comply with regulations (e.g., GDPR, HIPAA), and minimize downtime in production environments. It's critical for roles involving databases, cloud infrastructure, or DevOps, where data integrity and availability are paramount, such as in e-commerce platforms or financial systems.
