Dell EMC Associate – Backup and Recovery Solutions Design v2 — Question 36

What is the primary disadvantage of incremental backups?

Answer options

• A. time-consuming to restore
• B. contain only the blocks that have changed since the previous backup
• C. increased amount of data going across the network
• D. can grow to contain a large amount of data

Correct answer: A

Explanation

The correct answer is A, as restoring from incremental backups can be time-consuming because each incremental backup must be processed in sequence to restore the complete dataset. Options B and D describe characteristics of incremental backups rather than disadvantages, while option C is not typically a major concern of incremental backups compared to full backups.
