Unsolved Data Deduplication and Data Integrity Issues - Server 2012 R2
-
So this goes along with the topic I posted last week about dedup on Server 2012 R2, and I have some additional questions. My boss said he did some research on dedup and found numerous reports of people having data integrity issues with dedup enabled.
IE losing entire shares or volumes of information, or partial information etc.
Unfortunately our MSP of course was sitting here during the conversation and said "None of our storage guys enable it, so there must be a reason, but I don't know why"
Which kills me.
Does anyone have any reliable information on the integrity of Server 2012 R2 dedup that I can reference? Good documentation on how data integrity is checked, and alerted for problems etc?
I'm not able to find much at all besides good things, of the non descriptive variety. "data dedup and integrity is a great improvement"
-
Another question I have is does anyone have the DDPEval.exe tool that they can send to me?
This is the deduplication evaluation tool. \windows\system32\DDPEval.exe
-
I've created a 2012 R2 vm and installed the service just to get the ddpeval.exe file.
Still looking for feedback on Deduplication overall. Whitepapers, and integrity reports.
-
I'm unaware of any concerns at all about data integrity. Not even sure why it comes up, what would make them have concerns around it? If your boss knows of issues, he should produce those references because it's hard to prove something that doesn't exist (there are no integrity concerns so why would their be research papers on it?)
Also, like all things in IT, there is no one to do a study on this so there isn't going to be the kind of data either of you want.

Back between 1996 and 2002 I heard a number of horror stories about using data deduplication. That was a long time ago, and it's been used in many production environments since. If your boss remembers that era of computing and hasn't updated knowledge since... then yeah, I wouldn't trust it either.

Windows didn't have dedupe back then. So he wouldn't be outdated as much as confused if that were the case.

I'm currently running an evaluation against a relatively inactive share to see what we could save.
Only at 17% complete as of now.
