Backup Copy Job - Backup Jobs selected

I generally specify from Backup Jobs and select all of my jobs.  On occasion I do it from repository.  The initial seed can take a while if there are some large VM’s to copy there.  That said, I don’t get too worried after the initial seed is done unless the servers also have a high change rate and there’s always going to be a lot of data to be copied.  But that said, I don’t generally see a difference between splitting up jobs vs one job unless I’m using different retention policies for different machines or want to run on a different schedule such as periodic for some machines and immediate for others, or something like that.
