The needed Update KB3000850 to get the support, mentioned at the TechEd Barcelona 2014 Session about VDI, is coming across.
It’s included in the November 2014 update with roughly 700 megs.
You can find it via Windows Update or here.
Deduplication and virtualized backups were announced as new supported scenario at the TechEd 2014 embedded in a VDI and Deduplication session.
Actually it’s nothing new, it was basically working already and I’ve been doing this since the early days of preview 2012 R2.
But now it’s officially supported by Microsoft.
The basic idea is to lay down all backup VHDX made by DPM Server on Scale-Out-Fileservers.
So the SOF can do exactly the same what like in a VDI environment and dedup all the drives.
I can totally agree with dedup rates above 50% and up to 80% in real world scenarios.
