Backup doestn work on a new Machine

Hi,
i have a Big Problem with Urbackup. For my Customer i installed Urbackup Server and the Client on the same Machine to Backup this single Computer. The Pc runs Windows 7 X64 and Urbackup x64. The installation runs perfect and the configuratrion is allready great, but if i want to Backup the PC it gets an error Message at the End of the Backup and the Status Lamp changes every time to red.

Here the comuter Details:
There is only one Machine who runs Windows 7. I want to Backup C (System) and D ( Data) on G (External USB Backup Drive).

Does someone had the same Problem?

Screenshots of the Erros:

Hope someone could help me…

Thx Matze

The first error looks like it failed to write to G: during a backup. This is a server error. Maybe the USB connection is unstable?

The second error looks like it can’t find the volume you want it to backup up. You could have a look at the client log file. Maybe there is more info there: http://www.urbackup.org/Administration_Manual.php?lang=de#x1-440008.2
