Which of the following has the correct definition mapping?

A.
Full backup – Backups can be performed quickly, but restoration takes longer

B.
Incremental – For restoration, full backup is restored and then differential backup is restored

C.
Differential – Backs up files that have changed since the last backup (any backup)

D.
Differential – Backs up files that have changed since last full backup

Explanation:
Full Backup
– All files are backed up
– Fastest restoration process
– Takes the longest to perform backup
Incremental
– Backs up files that have changed since the last backup (any backup)
– Backups can be performed quickly, but restoration takes longer
– Full backup must be restored first and then each incremental backup
Differential
– Backs up files that have changed since last full backup
– For restoration, full backup is restored and then differential backup is restored
