Dell EMC Associate – Information Storage and Management v5 — Question 46

What is an advantage of performing incremental backups compared to cumulative backups for the same data?

Answer options

• A. Requires more time to perform data backup
• B. Storage capacity needed for backups is significantly reduced
• C. Requires more storage capacity for backup
• D. Reduces restore time but requires a maximum of two copies

Correct answer: B

Explanation

Incremental backups only save the changes made since the last backup, which significantly reduces the amount of storage needed compared to cumulative backups that store all changes. The other options either incorrectly suggest longer backup times or increased storage needs, which do not apply to incremental backups.
