View Amount of Space Saved by Data Reduction on a Volume
The percentage of space saved by data reduction for a volume is an estimate found by comparing the total amount of space
saved by compression and deduplication with the total amount of space processed by data reduction in the volume.
Steps
1. If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2. Click the Storage tab.
3. In the Storage tab navigation pane, select a volume.
4. In the right pane, click the Statistics tab. The space saved by data reduction on that volume is displayed at the bottom of
the Statistics tab.
Change the Default Data Reduction Profile
The default Data Reduction profile determines the type of data reduction that is applied to new volumes.
Steps
1. If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2. In the Summary tab, click Edit Settings. The Edit Storage Center Settings dialog box opens.
3. Click the Preferences tab.
4. From the Data Reduction Profile drop-down list, select the default profile for new volumes.

Pause or Resume Data Reduction
Pause Data Reduction on a volume to prevent deduplication and/or compression from running during data progression.
Pausing Data Reduction on a volume pauses deduplication and/or compression on all view volumes created from the original
volume. After pausing Data Reduction, compression and deduplication stop running on new data but the existing data is not
uncompressed.
Pause or Resume Data Reduction for a Volume
Pausing Data Reduction for a volume prevents compression and deduplication from happening until Data Reduction is resumed.
