2012 R2 Data Deduplication - Unoptimize single directory - part 2

$
0
0

This is a continuation of a similar post from Shaun TPG. 

I am attempting to un-dedup files that I recently added to my "excluded" parameters in my Dedup job settings (.pst's).  I excluded both "pst" extension types, and a specific folder.  Now I am trying to unoptimize these files that are still deduped.  I can see that my "InPolicyFiles" no longer matches my "OptimizedFiles"\

I have two questions:

- How do I determine which files are deduplicated and not?  I cannot run the cmdlet "get-dedupestatus" on a specific folder

- How do I expand a file that should no longer be deduped?  The cmdlet "expand-dedupfile" was mentioned in a previous thread.  However, when running on a specific file, I get no output.  I also included the "-asjob" function, but am unable to get any results from the "get-dedupjob".  The Optimized file total also does not change. 

- How do I expand an entire directory?  Even if I was able to get the cmdlet "expand-dedupfile" to work, when piping in a directory, the command returns error  "0x80070005 - Access is Denied".  I have verified ownership and full permissions, and running the command manually on an individual file works correctly.  The previous post about unoptimizing a single directory also has a user experiencing the same issue.  I should note that I do not get any "access denied" message when running the command on an individual file, although I still do not have any output/results.

Dedupe is really cool, but I've lost many files due to corruption, and beginning to rethink it's value in a production environment.

Thanks in advance.
