D2d and dedup ration

[scav0r]

Hi,

I have an D2D 2504i G2, problem is that it does not seem to report size correctly, I am running daily full backups on about 260 pr day, after 15 days(aprox 3900GB) The D2d system reports that it is full, I see the dedup ratio is 1.9, which seems very low, at the data does not change that much. However, if I go under Status and select Disk the report shows the following under the share i have created:
Share1 1336 5.2 TB 178.0 GB 29.4:1 which shows a dedup ratio of 29.4 which is much more realistic, size on disk is reported to 178GB. This is the only share on the server, where are the rest of the storage going?
