Dell EMC Specialist – Systems Administrator, VPLEX — Question 27

You are designing a cloud backup solution. Consider the following requirements when sizing the backup target:
✑ Total amount of data to be backed up = 2 TB (2000 GB)
✑ Full backup once a week
✑ Retention period for full backups = 2 months
✑ Daily incremental backups (assuming an average 10% change in data)
✑ Retention period for incremental backups = 1 month
✑ No Compression or deduplication
✑ Number of backup copies = 1
What is the total capacity, in GB, required for the backup target to accommodate the backups?

Answer options

Correct answer: C

Explanation

The correct answer is 21,200 GB because the total storage needed includes 8 full backups (2 TB each for 2 months) and 30 incremental backups (10% of 2 TB for 1 month). Other options do not account for the full and incremental backups correctly or miscalculate the total capacity required.
