Dell EMC Associate – Information Storage and Management v5 — Question 62

What is a benefit of differential backup over incremental backup?

Answer options

• A. Differential backups have longer restore times than incremental backup.
• B. Incremental backup can expand to contain more data than differential backup.
• C. Differential backup can expand to contain more data than an incremental backup.
• D. Incremental backups determine the backup copy used to restore the data.

Correct answer: C

Explanation

The correct answer is C because differential backups include all changes since the last full backup, which can lead to larger backup sizes over time. Options A and B are incorrect as they misrepresent the characteristics of backup types, while D inaccurately describes the function of incremental backups.
