Space usage reporting in Server 2012

I have a Server 2012 fileserver VM residing on a Nimble array. The server has a single share on the E drive. When viewed using the Properties window on the server the data stored is 7TB. However, when I use a backup utility to copy this data over to a Qnap it balloons to 13.5TB. Data deduplication is not installed.

Is the 7TB figure the real space required to store this data without any of the Nimble compression?

Could a difference in block size cause this increase in data storage requirements?

Thanks

DO you have shadow copy services on? Shadow Copies don't show up in space used, but will be backed up if backup software is not told to ignore them

It turned out I was backing up multiple copies from a SQL server that was using this server as it's backup target.

Thanks
