It is a cifs volume inside a vfiler. I followed the below steps:-
1. I mapped the share present inside the volume on to a windows server as it is a CIFS NAS volume.
2. I had 2.5 TB of files. I added these files to multiple compressed (.zip) files and the size of zip files after compression was around 500 GB. I expected the size of the volume/vfiler to drop by 2 TB after the next snapmirror transfer is complete.
3. The snapmirror is configured to run every 2 hours. Therefore, once the snapmirror transfer is complete the size should have decreases by 2 TB.
4. The volume has deduplication enabled.
Please suggest if the zip file is showing me 500 GB after compression why does the size of volume is still the same.
