I have had 3 different machines run full backups to the WHS.
My WHS currently has 1 HD at 160GB. The available diskspace in WHS console shows 130GB free out of 152GB, with 6GB taking up space for backups. I find this hard to believe when i ran a full backup of 72GB of data from one machine as well as 16GB of data from another. I understand the Single Instance Storage technology, however when i RDP into the WHS and I look at the available space on the hard disk via Windows Explorer, it represents a more accurate size, 52Gb FREE and about 100GB used.
Anyone have any insight on this?
