PostgreSQL Backup stuck at 88%

Hello, 

once again I have a strange problem. We have set up a PostgreSQL backup and wanted to create an initial full backup. Data was transferred and everything looked good so far. However, at 88% the job stops. Under Log for the Job I only get this information.

Has anyone encountered this problem before and could it be solved ? We have already reinstalled the agent but again without success. Our database admins don't have a solution either.

with kind regards
