4 Monitoring Deduplication, Compression and Performance
After backup jobs have completed, the DR Series Deduplication Appliance tracks capacity, storage 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
savings) on the initial backup. As additional full backup jobs complete, the ratios will increase. Backup
jobs with a 12- week retention will average a 15x ratio in most cases.
