Which of the following provides the correct characteristic for the specific data backup type?
A.
Differential process backs up the files that have been modified since the last backup
B.
Differential process backs up the files that have been modified since the last full backup
C.
Incremental process sets the archive bit to 1
D.
Differential process sets the archive bit to 1
Explanation:
A differential process backs up the files that have been modified since
the last full backup. When the data need to be restored, the full backup is laid
down first, and then the most recent differential backup is put down on top of it.
The differential process does not change the archive bit value. An incremental
process backs up all the files that have changed since the last full or incremental
backup and sets the archive bit to 0.
