"[Systems] PTS-Datenbank1_1"
Is this the path of the source or target datastore? What's the name of the other datastore?
the file exists on the datastore ...
Please post a list of all files (ls -lisa) which are still in the source folder.
If the flat file is still present, then compress/zip all the VM's .log files and attach the .zip file to your next reply post.
