Which of the following backup types automatically backs up the entire contents of the server being backed up?
A.
Full backup
B.
Selective backup
C.
Incremental backup
D.
Differential backup
Explanation:
A full backup backs up all contents of the server, or disk, or drive being backed up. This includes all directories, sub-directories, and files and data. When you need to perform a system restore, a readily available full backup copy allows you to perform the restore inthe least quantity of time.
Incorrect Answers:
B: A selective backup backs up the directories, sub-directories, and files that have been manually selected for backing up by an administrator.
C: An incremental backup backs up files that have been added and all data that have been modified since the most recent backup was performed.
D: A differential backup checks each file to determine whether it has been modified or not, since the last full backup was performed, and based on this determination, either includes or excludes the file in the differential backup.
