With Power Pack 3 some folders (like such named Temp) will be backed up, which have been ignored before and so had a bad influence on the restored system in a few cases.
That's it. I have a "work" temp folder which is not the one %temp% points to. This folder has a LOT of data in it and was never intended to be backed up. With PP2 it was skipped simply by being called Temp. Explicitly adding an exception for that folder got the backups up to speed again.
Thanks
