Backups are copies of data or system configurations created and stored separately from the original. This process ensures that information can be recovered in the event of data loss, corruption, or system failure. Backups are typically performed on a schedule, ranging from daily to hourly, and can be stored locally, on network attached storage, or in cloud environments. Implementing a robust backup strategy is crucial for business continuity, disaster recovery, and maintaining operational integrity. For instance, a company might back up its customer database every night to prevent data loss from hardware failure. Unlike snapshots which capture a point in time for quick rollback, backups are designed for long term retention and recovery from more severe incidents. Concepts related to backups are frequently tested in cybersecurity certifications like CompTIA Security+ and cloud certifications such as AWS Certified Solutions Architect Associate.
