Final answer:
The correct answer is D) Incremental backup, which copies only the changes made since the last full or incremental backup. It is efficient in terms of storage space and backup time.
Step-by-step explanation:
The correct answer to the question is D) Incremental backup. An incremental backup is a type of backup that copies all changes made since the last full backup. This means it only backs up files that have been changed or created after the most recent full or incremental backup, which can save significant storage space and reduce the time needed to complete the backup. On the other hand, differential backup saves changes made since the last full backup, but does not consider any incremental backups that may have been made in the interim. It also saves all changes each time, making it quicker to restore from than an incremental backup, but larger in size because it accumulates changes. Archive is a long-term data storage, cloud computing refers to the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.
