To perform ASIS deduplication of Secondary Snapshots, the Plug‑in for SnapVault Manager must be configured to instruct the Secondary Filer to create a deduplicated snapshot. This configuration is done by setting the Enable A-SIS Deduplication of Secondary Snapshots check box in the Configure window. For more information about this option, see Configuring default settings.
If the Enable A-SIS Deduplication of Secondary Snapshots check box is selected, deduplication of the Secondary Snapshot occurs, but only if the filer has the ASIS license installed and the target volume has ASIS enabled. Initially the filer creates an archive snapshot, ASIS deduplication of this snapshot is performed. After it is successfully completed, the archive snapshot is replaced with the deduplicated snapshot. If the target filer is not licensed for ASIS or the target volume does not have ASIS enabled, deduplication does not occur.
If the Enable A-SIS Deduplication of Secondary Snapshots check box is not selected, deduplication of the secondary snapshot does not occur, even if the filer has the ASIS license installed and the target volume has ASIS enabled.
