Joe_Miner Posted June 24, 2013 Share Posted June 24, 2013 I was wondering what kind of deduplication rates people were seeing in Server 2012 with the Data Deduplication Role enabled. I'm seeing volumes with dedup rates of 78%, 79%, and 86% which are mainly saved Hyper-V clients, testing databases, and BDBB's I'm saving http://homeservershow.com/windows-server-2012-and-data-deduplication.html Link to comment Share on other sites More sharing options...
jmwills Posted June 24, 2013 Share Posted June 24, 2013 What can you de-dedup from a Hyper V Client? Link to comment Share on other sites More sharing options...
Joe_Miner Posted June 24, 2013 Author Share Posted June 24, 2013 I was referring to Exported copies of Hyper-V clients that I save. Link to comment Share on other sites More sharing options...

GavinCampbell Posted June 25, 2013 Share Posted June 25, 2013 Does this role impact performance? Link to comment Share on other sites More sharing options...
Joe_Miner Posted June 25, 2013 Author Share Posted June 25, 2013 I'm sure there's impact but on my S2012 storage server it's running on a N40L and I have Server Backup running at night plus one running Hyper-V client at the moment -- I'm not seeing the impact but I'm sure it's there.

ikon Posted June 25, 2013 Share Posted June 25, 2013 If you can't see it, it doesn't exist... well, from a practical point of view anyway Link to comment Share on other sites More sharing options...
MicroMatt Posted June 25, 2013 Share Posted June 25, 2013 You can run the DDPEval.exe tool "When the deduplication feature is installed, the DDPEval.exe tool is automatically installed to the \Windows\System32\ directory." Running this from the command line will give you an idea of how much space you can save. You can also run it against a variety of storage types which gets even more interesting. I'll have to run it in a bit and post my numbers. Matthew Link to comment Share on other sites More sharing options...
