Options
- ADifferential
- BFull

- DIncremental
Explanation
A differential backup saves all data changed since the last full backup, making it the correct choice when the comparison point is specifically the most recent full backup.
Common mistakes.
- B. A full backup copies all data regardless of previous backups and does not perform a change comparison against a prior backup.
- C. A clone backup creates an exact sector-level copy or mirror of the entire data source, not a change-based comparison against a prior backup.
- D. An incremental backup saves only changes since the last backup of any type - whether full or incremental - not specifically since the last full backup.
