Background for this topic.
Backup is the process of creating copies of digital data to restore it if the original is lost, corrupted, or altered. These copies can be stored locally, remotely, or in the cloud and are made using methods like full, incremental, or differential backups to optimize storage and recovery time. Backups ensure data availability after hardware failures, accidental deletions, or malicious events that compromise original files.
From a security perspective, backups must be protected against unauthorized access and tampering, as attackers may target backup systems to disable recovery or steal sensitive information. Effective defenses include encrypting backup data, enforcing strict access controls, and maintaining isolated or immutable backups that cannot be altered or deleted by malware. Regularly testing backup restoration is critical to verify data integrity and ensure reliable recovery during incidents.
