Database Backups
Database backups are the process of creating and storing copies of a database's data and schema to protect against data loss, corruption, or disasters. This involves capturing a point-in-time snapshot of the database, which can be restored to recover information in case of hardware failures, human errors, or cyberattacks. Backups are a critical component of data management and business continuity strategies.
Developers should learn and implement database backups to ensure data integrity and availability, especially in production environments where data loss can have severe financial or operational impacts. Use cases include compliance with regulations (e.g., GDPR), disaster recovery planning, and mitigating risks from accidental deletions or system crashes. Regular backups are essential for applications handling sensitive or transactional data, such as e-commerce platforms or financial systems.
