Dell EMC Specialist – Systems Administrator, PowerProtect DD — Question 8

A backup administrator is tasked with monitoring PowerProtect DD capacity metrics. The administrator is backing up 2 TB 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

Correct answer: B

Explanation

The correct answer is 220 GB, which accounts for the compressed size of the incremental backups after six days (20 GB each) and the weekly full backup (100 GB). The other options do not accurately calculate the total capacity used after the backups are considered, leading to incorrect burn rate figures.
