Feature Request: ReFS Support for BitLooker

[davewelsh]

BitLooker speeds up my backup jobs quite a bit for most of my VMs. One of my VMs has a large ReFS-formatted disk that's mostly empty and BitLooker doesn't detect the deleted blocks. If BitLooker could support ReFS that would cut my backup time in half.

As of now BitLooker support only NTFS one of reasons being the fact that ReFS has been revised seriously in Windows Server 2016.

By the way, speaking about Windows Server 2016 and ReFS, I'm not sure whether MS itself thinks about ReFS as a good candidate for a guest file system, and not as a primary system is a file system to host Hyper-V VM.

Thanks.
