32 Setting Up the Dell™ DR Series System as a Backup to Disk Target on

Symantec Backup Exec 2012 and 2014 | January 2014

6 Monitoring deduplication, compression, and performance

After backup jobs have run, the DR Series system tracks capacity, storage savings, and throughput on the

DR Series system dashboard. This information is valuable in understanding the benefits of the DR Series

system.

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 are completed, the ratios will increase.

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