QuestionQ51

Storage Design and Tuning

Assume that a customer uses 1,000 GB of capacity for the initial backup, has an average daily data growth of 10 GB, and configures a backup policy to run a full backup every Monday and an incremental backup for changed data every Tuesday through Sunday. Also assume that both full and incremental backups have a four-week data-retention period.

If deduplication, redundancy ratios, and replication are excluded, what is the minimum required back-end capacity?

Explanation

Four retained Monday full backups grow by 70 GB per week: 1,070 GB, 1,140 GB, 1,210 GB, and 1,280 GB, for 4,700 GB total. The four-week retention period also retains 24 Tuesday-to-Sunday incremental backups, totaling 24 × 10 GB = 240 GB. The required capacity is therefore 4,940 GB.
