2012 R2 HyperV - How to apply deduplication to HyperV VM

Microsoft introduced deduplication in Windows 2012. 

In the first version deduplication concerned unstructured data, so in practice the server, but excluding the Exchange and SQL servers.

But in the version of Windows 2012 R2, Microsoft is introducing a specific support for the deduplication of virtual machines.

In fact, if you try to bring deduplication of a volume, including the options of the first "down" item appears Virtual Desktop Infrastructure (VDI) server.

This is because the VM is an ideal candidate for deduplication; in particular for the disk c: \ virtual machine (VHD and VHDX).

To utilize most of this features, here are a couple of tips:

  1. the virtual machine disks (VHD and VHDX) must NOT be placed on the same disk c: \ where runs Hyper-V, these volumes of deduplication is not supported; then you must create a new one and put yourself VMs.
  2. program the scheduler deduplication to a time "convenient" deduplication in fact requires a certain commitment of the CPU; then maybe schedule deduplication at night can be a good idea.

If you want to program the scheduler go in file & storage services.
