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?
