Sometimes you have to give up a technique, because it does not fit all ...... .
Today, I had to remove Windows Server 2012R2 deduplication, this is a very clever technique that can reduce the use of disk space. My program drawback is that it also seems to lead Windows Server Backup a lot of running to slow down, even though it saves a lot of disk space (for my 60 %), but it means that you must close the Hyper V instance. I certainly hope that the Windows 10 Server in Microsoft enables us to real-time HyperV guest systems (rather than just VDI instance) on better use of deduplication.
Anyway ...... focus of this article is more for my own future reference, it may help other people from Server 2012 R2 to delete duplicate data is deleted.
Disabling will not delete duplicate data " to cancel the repeat " have " duplicate " data.
If by GUI or Powershell disabled deduplication, it actually does not undo the work done. Worse, if the feature is disabled, you will not be able to run garbage command (the command will clean up the delete duplicate data created by the technical data).
Therefore, be sure to enable the deduplication functionality, but first want to exclude an entire drive, which is very important. Then, run the following two commands (run will take longer, depending on the amount of data you have).
unoptimise command:
start-dedupjob -Volume <VolumeLetter> -Type Unoptimization
Check the status:
get-dedupjob
Rubbish:
start-dedupjob -Volume <VolumeLetter> -Type GarbageCollection
Check the status:
get-dedupjob
After completion of the two operations will take some time, you can delete the duplicate data is deleted from the server role.
