In my experience backing up multiple hosts to a single host can speed
things up. Especially if using rsync over ssh with multiple CPUs on the
single host. You would need to do some experimentation to determine the
best number for your hardware and network. Also, if you exceed that
number you can put more stress on the backup machine lessening the
impact to the hosts being backed up.
