Các lựa chọn
AA differential backup contains all files changed after the last full backup, while an incremental backup saves all files changed after the last full, differential, or incremental backup.
BA differential backup may take longer to restore files than an incremental backup, because the most recent versions of files are spread across a larger number of backup sets.
CA multiplexed backup is used as a mixed combination of a full backup, a differential backup, and an incremental backup.
DAn incremental backup tends to take longer to get backup files than a differential backup, because more files are copied during each backup.
