View efficiency space savings

You can view the amount of space savings achieved through deduplication and data compression on a volume by using the volume show command.

About this task

The space savings in Snapshot copies are not included when calculating the space savings achieved on a volume. Using deduplication does not affect volume quotas. Quotas are reported at the logical level, and remain unchanged.

  1. Use the volume show command to view space savings achieved on a volume using deduplication and data compression.


The following command enables you to view the space savings achieved by using deduplication and data compression on volume VolA: volume show -vserver vs1 -volume VolA

cluster1::> volume show -vserver vs1 -volume VolA

                                 Vserver Name: vs1
                                  Volume Name: VolA
            Space Saved by Storage Efficiency: 115812B
       Percentage Saved by Storage Efficiency: 97%
                 Space Saved by Deduplication: 13728B
            Percentage Saved by Deduplication: 81%
                Space Shared by Deduplication: 1028B
                   Space Saved by Compression: 102084B
        Percentage Space Saved by Compression: 97%
