We have a Windows 2012 Veeam Server with a volume that we use to store our backups on. The volume has a capacity of 14.9 TB and has data deduplication enabled.
On the volume there are folders for the different backup jobs. These folders have a smaller size on disk than their actual size due to data deduplication. The sum of the size on disk of all the folders is about 8 TB, but windows shows that there's only 64 KB free space left on the disk.
The folder option to show hidden files, folders and drives is enabled.
Does anyone know how I can see why there's a discrepancy between the sum of the size on disk of the folders and the free space left on the disk?
