savings and throughput on the DR Series Deduplication Appliance dashboard. This information is
valuable in understanding the benefits the DR Series Deduplication Appliance.
NOTE: Deduplication ratios increase over time; it is not uncommon to see a 2-4x reduction (25-50% total

jobs with a 12-week retention will average a 15x ratio in most cases.
