Backing up a local Drivepool using CloudDrive?

Question

So I have an 8TB local drive pool composed of 4 different HDD's of varying size. I would like to backup several TB's of this data to my google drive using Drivepool's folder duplication. When I select a folder to duplicate, the folder is copied into CloudDrive's upload queue and Drivepool shows the duplicated data as being present on my CloudDrive and another duplicated copy is also split among the local HDD's making up the local pool (I assume because the duplicated data still needs to be uploaded), essentially showing two duplicated copies of the amount of data I selected instead of just one.

However, once a folder has finished being duplicated and CloudDrive's "to-upload" queue is 0 bytes, Drivepool still shows that the duplicated files are being stored on my local HDD's in addition to my Clouddrive. How can I get the duplicated data to be stored only on my CloudDrive, and have the duplicated folders be deleted locally after they are uploaded in order to prevent having any duplicated data stored on my local drives outside of my CloudDrive cache?

What I've done:

- Disabled plug-in settings that can force immediate balancing

- Set my CloudDrive to only contain duplicated data while the local drives can only store unduplicated data under Drive Usage Limiter settings.

Given that my 8TB capacity drive pool is about 6TB full, if I try to duplicate 2TB of data to my CloudDrive then my local Drivepool will be totally full because a second copy of the 2TB duplicated data is being stored on my local drivepool too.

 

Edit: I solved my question by using pool hierarchy. This article helped a lot: https://blog.covecube.com/2017/09/stablebit-drivepool-2-2-0-847-beta/

just to clear up something, the "duplicated data" isn't the "second copy". StableBit DrivePool doesn't have a concept of original and copy.

It applies to ALL copies of the file. It means that there is data on the drive that has been duplicated.

So does that mean then if I duplicate my entire local drivepool to my clouddrive, then drivepool software will show my entire local drivepool as containing only duplicated data? 

I've also noticed that two of my HDD's are showing as having over 100GB+ of "other" data on them, however when examining the drives using WinDirStat, only the unduplicated data can be seen and the extra "other" data is no where to be seen on the drives. Is this a Drivepool visual bug? The total disk usage reported from WinDirStat matches the numbers reported in Drivepool excluding the 'other' data. So basically WinDirStat sees all of the normal data contained in my drive, however the extra 100GB of other data is no where to be seen.
