 +====== Disable Data Deduplication ======
 +In order to “re-hydrate” the data back to the original files and out of the deduplication store, use the powershell command: **start-dedupjob -Volume -Type Unoptimization**
 +You can check the status on where this is at by using **get-dedupjob**,​ or, a free tool like WinDirStat which shows the size on disk of specific files.
 +At this stage – you may notice the original files getting bigger, but the dedup store (and the chunks within it) is not decreasing at all.
 +There are two additional job types available, “**garbageCollection**” and “**scrubbing**”. ​
 +[[http://​​WindowsServer2012/​DedupandWindowsServer2012.html]] **GarbageCollection** will find and remove unreferenced chunks and scrubbing will perform an integrity check
 +Run **start-dedupjob -Volume -Type GarbageCollection** – this must be done with dedup enabled, so in order to prevent further data deduplication,​ enable data deduplication,​ but add all folders to excluded folders list and then run the command.
 +Now use **get-dedupjob** to see the status. Once this completes (it will take a while) – disable dedup again.
