I see from your comments/logs that "I missed it by that 🤏 much"™

Yeah, I guess with a `RunsWhen = before`, we might not have the jobid/ujobid yet, but I thought we would/should...

I guess I was just thinking to set the client back to unlimited at the end of the job. OCD... Making sure to clean up, put 
things back where I found them.

But, as I think about this now, what if you run a job that sets the client to limited, then later in the day (or whenever, 
but before the next backup job runs) you need to do a restore. If the bandwidth limit applies to restores too*, you will be 
stuck with a slow restore.

*Note: This is a good question that I don't immediately know the answer to, but my first guess would be yes, but I am not sure.

Yeah, this is good news!  Glad it works for you now!

Yeah, the bandwidth limit does not affect/throttle this accurate info data transfer from the Director to the client.

I can't imagine this would be a big deal, but if it is something that is really adversely affecting your environment, you can 
always open a feature request. :)


Best regards,
