the retry is the the normal retry after 10 minutes. Two of the Enponits has no retry forced after the failure (don't ask me why).
If it is realy only the first run after upgrade, then we could see it later this day, because the first endpointjob after the upgrade runs today at 17:50 for one of the endpoints for the second time.
If it works proper at the second run, what about the backupchain then? Is it valid?
P.S.: For the support-case i should upload the logs, but actually I'm out of office, so I could only upload the logs later this day.
