a huge of event log entries while running a backup task

Hello All,

I've got a lot of Windows event log entries (1.600) while running a backup task. Here the text of the event:

Fehlercode: 17
Die spezifizierte Datei existiert nicht.

The task is started by using acrocmd run task --ID=xxx and is running fine, but generates a lot of warnings or errors sucks. Is there a way to prevent it?

The folder C:\ProgramData\Acronis\BackupAndRecovery\MMS\TasksStorage exists and the user, who is running the task, have all privileges on that folder.

We are using 11.0.17217 of Acronis Backup and Recovery, running on Windows 2008 SBS, german. Actual we are using a trial licence, full version is ordered already. Trial version is running for 10 days. So 5 days should be left.

It would be fine to get a response.

Thanks, Holger
