Backup and Restore
Backup and restore is a fundamental data protection strategy that involves creating copies of data (backups) to safeguard against loss, corruption, or disasters, and the process of recovering that data (restore) when needed. It ensures business continuity by enabling recovery from hardware failures, human errors, cyberattacks, or natural events. This concept applies across various technologies, including databases, file systems, cloud services, and applications.
Developers should learn and implement backup and restore strategies to protect critical data in production systems, comply with regulatory requirements (e.g., GDPR, HIPAA), and minimize downtime during incidents. It is essential for disaster recovery planning, database management (e.g., in PostgreSQL or MongoDB), and cloud deployments (e.g., AWS S3 backups), ensuring data integrity and availability.
