As part of my certification studies, I decided to give a try on storage pools and file deduplication.
A simple scenario, with a standalone server and three (virtual) disks. You can’t use deduplication on system disks, so I added two 127 Gb volumes, thin provisioning.
They show up in Server Manager:
I have created a storage pool:
And a new volume, for which I picked the mirror option (RAID 1 equivalent):
Make sure you pick NTFS as your file system.
Before enabling the dedup, I created three folders and copied the same content to each one of them: family pictures!
Ok. When everything is in place, all you have to do is enable the deduplication for that volume:
I have set the days to 0, to see immediate results.
And to speed things up, you can manually start the dedup job:
Try a few times, until you see it is running:
Then you can check the status:
You can also check it here, in the Volume properties:
There you go!
Not too hard.
