Backup

Backup is the process of creating copies of data to protect against loss, corruption, or disasters, ensuring data can be restored if needed. It involves strategies like full, incremental, or differential backups, often stored on separate media or locations. This concept is critical for business continuity, compliance, and risk management in IT systems.
