One other point that I don't think has been mentioned yet is that if you 
have configured only one concurrent backup, something that slows down a 
single host like a big upgrade or set of new files to the point where it 
takes the whole backup window will cause the backups scheduled later to 
be missed.   A little more obviously, if you are running some remote 
backups over slow links you probably want them to run concurrently with 
local runs since their disk use will be throttled by the bandwidth limit.
