Why each option

Full and Incremental backup types will clear the archive bit on files after they are backed up.

ACopy

A copy backup copies all selected files but does not clear the archive bit, preserving its state for other backup types.

BFullCorrect

A full backup copies all selected files to the backup medium and then clears the archive bit for each file, marking them as backed up. This ensures that subsequent differential or incremental backups accurately track changes since the last full backup.

CSnapshot

A snapshot captures the state of a disk or volume at a point in time and does not typically interact with or reset individual file archive bits.

DIncrementalCorrect

An incremental backup copies only files that have the archive bit set (indicating they have changed since the last full or incremental backup) and then clears the archive bit for those specific files. This makes it efficient for daily changes but requires all prior backups for a full restore.

EDifferential

A differential backup copies all files that have changed since the last full backup but does not clear the archive bit, ensuring they are included in subsequent differential backups until a new full backup occurs.
