Abstract: The rapid dependence on smartphones for storing personal and professional information has introduced new risks during emergencies such as device loss, battery failure, or network unavailability. Xaanaax is a digital emergency backup and information access system designed to ensure uninterrupted availability of essential files, contacts, and notes anytime and anywhere. The platform offers secure, centralized cloud-based storage with 24/7 accessibility across devices. This survey paper reviews existing digital storage and backup solutions, identifies their limitations in emergency scenarios, and analyzes how Xaanaax addresses these gaps through its architecture, security mechanisms, and user-centric design.
