Windows 2012: datastore deduplication

Hi,

I'm running Windows 2012 on my laptop (not R2, should I? why?).
Please don't ask why, I like to do so for a number of reasons.

Now, there is this new 2012 feature to do deduplication: http://technet.microsoft.com/en-us/library/hh831434.aspx 
I wonder if it's worth to run it on a laptop since it's not on all the time (and if I understand well, it needs to run deduplication at time when machine is not/less used).
On the other hand, I have 1 TB of internal disk (os is on SSD) which is filled up with virtual machines (vmware workstation, no hyper-v yet -working on that-).
These fill up almost 500 GB and it would be nice to have some more space ....

Please advise.
J.

2012 does not support deduplicating VMs,, so no, given your scenario, I would not configure it.

What is your source of this? What does it then deduplicate? It certainly deduplicates hyper-v machines, so no vm's (http://searchservervirtualization.techtarget.com/photostory/2240148767/Top-five-Hyper-V-30-features-that-will-excite-IT-pros/2/Five-best-Hyper-V-30-features-Deduplication)?

My source is from discussions I've had with the hyper-v team. Your link was a third-party, not Microsoft and was written before 2012 was even released. To quote the article:

"It’s still unknown whether it will be possible to dedupe live VMs on a volume in Windows Server 8 RTM because of the potential for I/O performance degradation. But it’s certainly possible in the release candidate. Even if this capability is not supported or recommended..."

They blatantly admit they didn't know of deduping VMs would work or be supported. And I can tell you it isn't.  But if you want more, here you can see (from Microsoft) their intended scenarios. Deducing VDI was only added in 2012 R2, and deducing multiple server VMs is still not a scenario they have officially announced any consideration for.
