Backups refer to the process of creating copies of data or entire systems to ensure that information can be restored in the event of data loss, corruption, or system failures. In both personal computing and enterprise environments, regular backups are considered a best practice for mitigating risks associated with accidental deletions, hardware malfunctions, and cyber-attacks such as ransomware. There are various types of backups, including full backups, which copy all data, and incremental or differential backups, which only save changes made since the last backup. Backups can be stored on different media like external hard drives, network-attached storage, or cloud-based services. For critical systems, backups are often stored in multiple geographical locations to protect against site-specific disasters like fires or floods. A well-designed backup strategy is a cornerstone of business continuity and disaster recovery plans, helping organizations and individuals recover more quickly from unexpected data loss events.
