Deduplication calculation on Appliance

[rVikas]

Hi Team,

I would like to know how to calculate dedupe data

For e.g

I have below data

dp_disk_xxx1    228,643 (GB Stored Pre-Dedupe)

dedupe-rate  by storage server

xxx1  94.03

so here how will i calculate actual data stored on appliance.

the above data i got from running Netbackup Analysis Tool (NBAT) provided by VERITAS.

Easiest way is to simply run the dedupe report from the CLISH.

NBAT also shows detailed real-time deduplication rates in the report (by storage server and client type) and also provides even further granular details in the analysis 'dedup_reports' folder
