[Server 2012 R2 Deduplication and DrivePool]

For those looking into this article in the future - yes this is possible, but you must configure DrivePool to use the NtfsFilters rather than bypassing them and going straight to disk.

 

From article:

http://community.covecube.com/index.php?/topic/962-server-2012-r2-data-deduplication-w-drivepool/

 

However, you will need to make one change first to ensure that it works properly:

Set "CoveFs_BypassNtfsFilters" to "false", and reboot the system.

 

I am currently receiving up to 70% savings from deduplication, and have 3 drives in my pool.
