Koenig,
it looks like you are not getting the installer program started. Try to download the zip file from the first post, unzip and run install.exe.
Gilean, I do not have time right now for any changes, but you can do that in scripts. Check the manual about the script names, which are called before and after a backup operation.
That did the trick thank you!!
Strange it didn't work through the pluginmanager....
