Hi,
i have a really strange problem:
Sometimes the transfer of the archive to Amazon AWS fails. In the details i get the error message:
Exception chain:
- Der Wert darf nicht NULL sein. Parameter name: source
- Mindestens ein Fehler ist aufgetreten.
and for every machine i get a mail
Quest Core auf BACKUP hat das Error-Ereignis "Core backup has failed" gemeldet:
Datum/Uhrzeit: 05/03/2019 01:00:07 +02:00

I found out that the problem only occurs when a machine was offline for >1 day. Then this error occurs for every machine. When i deselect the offline-machine then the transfer to AWS works again.
In my case oneworkmate was out of office for a few days. After the machine was offline for a day the transfer failed. I removed his machine from the archive and forced a transfer and everything worked again.
The same problem occored with the machine of another workmate.
The Core- and Agent-versions are 6.2.1.0.0
