A backup strategy that saves only the data that has changed since the most recent backup, whether that was a full backup or a prior incremental backup. Compared to full backups, incremental backups reduce storage usage and backup time. However, restoring data requires sequentially applying the full backup followed by every subsequent incremental backup, which can make recovery more time-consuming.
