I've been testing out Windows Server Backup solution on a 2008r2 server. I've scheduled a daily backup covering everything on C:, bare metal and a couple of folders.
When I open the snap-in, it currently says that I have 10 copies, which are using 300 GB disk space. However, when I go to the volume where the backup is located, and check the file size of "WindowsImageBackup" folder, it's only 50gb, which is roughly 1 copy.
I can't figure out a rational explanation for this.
