C. Incremental Explanation: In incremental backup, only the data that has changed since the last backup (whether it's a full backup or an incremental backup) is backed up. Additionally, the archive bit associated with each file is typically reset after the data is backed up. This ensures that during subsequent incremental backups, only the files with the archive bit set (indicating they have been modified since the last backup) are included in the backup. Differential backups do not reset the archive bit. Instead, they back up all the data that has changed since the last full backup, regardless of whether the archive bit is set or not. Snapshot and synthetic full backups are backup techniques rather than backup types. Snapshot backups capture the state of a system or data at a specific point in time, while synthetic full backups involve creating a full backup from a combination of incremental or differential backups. Neither of these backup techniques inherently involve resetting the archive bit.
