There are several types of data backups, each with its own advantages: - Full Backup: A complete copy of all data. It is comprehensive but time-consuming and requires significant storage space. - Incremental Backup: Only data that has changed since the last backup is copied. It saves time and storage but requires a sequence of backups to restore. - Differential Backup: Copies data changed since the last full backup. It is a middle ground between full and incremental backups in terms of time and storage.
