Which backup takes longest to complete?
- A.
Incremental
- B.
Daily
- C.
Full
- D.
Differential
Correct Answer
C. FullExplanation
A full backup takes the longest to complete because it involves backing up all the data and files on a system, regardless of whether they have changed or not. This means that every file, folder, and database is copied to the backup storage, which can be time-consuming, especially for large amounts of data. In contrast, incremental, daily, and differential backups only copy the files that have changed since the last backup, resulting in shorter backup times.Rate this question:
