Enable Data Reduction on a NAS Volume

Data reduction is enabled on a per NAS volume basis.

1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, expand NAS Volumes and select a NAS volume.
4. In the NAS Volume panel, click Edit Settings.
   The Edit NAS Volume Settings dialog box opens.
5. Click Data Reduction.
6. Select the Data Reduction Enabled checkbox.
7. For the Data Reduction Method field, select the type of data reduction (Deduplication or Deduplication and Compression) to perform.
   Deduplication and compression will usually save more space, but more resources will be used during data reduction and during reads of data that was compressed, possibly reducing performance.
8. (Optional) Configure the remaining data reduction attributes as needed. These options are described in the online help.
   • To change the number of days after which data reduction is applied to files that have not been accessed, type the number of days in the Exclude Files Accessed in the Last field. The number of days must be at least 1.
   • To change the number of days after which data reduction is applied to files that have not been modified, type the number of days in the Exclude Files Modified in the Last field. The number of days must be at least 1.
9. Click OK.
