We have a test hyper-V for various VMs. It is naturally easier for us to start from Parent disk which is sys prepped and move on.
On the other hand, deduplication(2012 R2) claims to be most effective on VHD library data.
Is the effectiveness of deduplication different when it comes to differencing VHDs as compared to other disks ?
Assuming it only works when VM is once off but then What is the algorithm ? and how much time it takes to de-dupe. What happens when the original old files (referenced chunks) are updated ?
