Backup Systems
Backup systems are software or hardware solutions designed to create and manage copies of data to protect against loss, corruption, or disasters. They enable data recovery by storing backups on local devices, remote servers, or cloud storage, often with features like scheduling, encryption, and versioning. These systems are critical for ensuring business continuity, compliance, and data integrity in IT environments.
Developers should learn backup systems to safeguard codebases, databases, and configurations from accidental deletion, hardware failures, or cyberattacks like ransomware. They are essential in production environments for disaster recovery plans, ensuring minimal downtime and data loss. Knowledge is particularly valuable for DevOps, sysadmins, and anyone managing critical infrastructure or cloud deployments.
