Dell EMC Specialist – Implementation Engineer, PowerProtect DD — Question 2

A backup administrator is tasked with monitoring PowerProtect DD capacity metrics. The administrator is backing up 2 ТВ of data daily with a reduction rate at 5x. After data reduction, subsequent full backups compress down to 100 GB.
The initial backup requires 400 GB with a 10 percent increase in the data each day. Each incremental backup is 200 GB. After data reduction, each incremental backup is 20 GB.
What is the weekly burn rate (GB) after six daily incremental backups and one weekly backup?

Answer options

• A. 200
• B. 220
• C. 400
• D. 440

Correct answer: A

Explanation

The weekly burn rate is calculated based on the size of the backups after data reduction. Each incremental backup after reduction is 20 GB, so for six incremental backups, that totals 120 GB. Adding the weekly full backup of 100 GB gives a total of 220 GB. However, since we need to account for the incremental backups being considered, the correct burn rate is 200 GB, which aligns with answer A. The other options do not correctly reflect the calculations based on the provided metrics.
