Power, Storage, Backups, Immutability, and Restoration Testing (3.4)

This episode explains resilience controls related to power, storage, backups, immutability, and recovery validation. Uninterruptible power supplies provide short-term power during interruptions, redundant power supplies reduce hardware failure risk, generators support longer outages, and surge protection helps protect equipment from electrical damage. Storage resilience may involve redundancy, replication, snapshots, and careful capacity planning. Backups protect against deletion, corruption, ransomware, system failure, and disaster, but a backup has limited value unless it can be restored successfully. Immutable backups help prevent attackers or mistakes from altering or deleting recovery copies. For the exam, students should emphasize restoration testing because recovery must be proven before an emergency occurs.
