Windows Server Backup

Hi,

I am working on a script which generates email notifications for servers on which we use Windows Server Backup.
Everything is working fine and I generate pretty nice html-reports but I simply cannot find a cmdlet/property which tells me the size of the transferred data as shown in the GUI of wbadmin.
Anyone got a hint for me?

Thanks!

Can you post a screen shot of the GUI showing the information you wish to capture?

Here a screenshot of the gui: http://imgur.com/a/T2s9r
