Configuring deduplication on a volume
If you have not configured deduplication when you created a volume, you can do so later from the Edit volume dialog box. Deduplication saves storage space by eliminating redundant data blocks within a FlexVol volume.
Steps 
1.
From the Home tab, double-click the appropriate storage system.
2.
Ensure that the left navigation pane displays the Vservers hierarchy.
3.
In the navigation pane, select the Vserver and click Storage > Volumes.
4.
Select the volume for which you want to configure deduplication.
5.
Click Edit, and then click Storage Efficiency.
6.
Select Enable storage efficiency.
7.
Select one of the following schedules:
•
On-demand
•
Automated
Deduplication is automatically run when 20 percent new data is written to the volume.
•
Scheduled
8.
If you choose the Scheduled option, select the storage efficiency policy.
9.
Click Save and Close to save your changes.
