What is Backup?
Backup is a process and technology set that creates and maintains copies of data, applications, or system states so an organization can restore them after data loss, corruption, security incidents, or operational failures.
Backup creates secondary copies of data or system images at defined intervals and stores them on separate media or locations. It supports recovery after events such as accidental deletion, hardware failure, or ransomware, and typically follows defined retention policies.
Backup methods include full, incremental, and differential backups, as well as image-based and file-level approaches. Architectures often use on-premises (on-prem) storage, offsite repositories, or cloud services, and apply encryption, access control, and integrity checks.
Enterprise Usage and Architectural Context
Enterprises use backup as part of broader data protection and cyber resilience strategies aligned to recovery time and recovery point objectives. Backup integrates with production systems, storage platforms, hypervisors, databases, and Software-as-a-Service (SaaS) applications.
Architectures often implement the 3-2-1 pattern or similar practices, maintaining multiple copies across different media and locations. Organizations coordinate backup with Disaster Recovery (DR), business continuity, archival, and records management processes and policies.
Related or Adjacent Technologies
Backup relates to DR, which focuses on restoring entire services or sites, and to business continuity, which focuses on maintaining operations during disruption. It also relates to replication, snapshotting, and continuous data protection, which support varied recovery objectives.
Backup interacts with storage systems, endpoint protection, Security Information and Event Management (SIEM) tools, and incident response workflows. It also intersects with compliance tooling for retention, legal hold, data governance, and privacy requirements.
Business and Operational Significance
Backup supports protection of business data against loss from hardware failure, user error, software defects, and cyberattacks, including ransomware. It enables restoration of systems and datasets to known-good states that meet defined recovery policies and objectives.
Regulators, standards bodies, and industry frameworks reference backup and recovery capabilities in requirements for information security, operational resilience, and data retention. Effective backup design and testing support audit readiness and risk management across the enterprise.
