You say the jobs fail. What is the "failure"? Error message?

I suggest creating scripts on the client, and moving these commands
into those scripts. It makes the JobDefs easier to read. Sure, you
have to copy stuff to the client, but I think that's cleaner.
YMMV.

This looks like an OS issue, not a Bacula issue. I suggest following
