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:
- 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.
- 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.
