Hello Chris, Many thanks for the input. You are right: things are working if I place the shell commands in a script instead of trying to pass them directly with bacula. The second mistake I made is not setting "RunsOnClient" to "No". The default seems to be "Yes". Either I missed this or the documentation is not very clear about the default value of "RunsOnClient".
