You need careful testing and understanding to not actually slow down  
your backups because of concurrency. If you do not use data encryption  
most of the time the I/O will be your bottleneck and it doesn't help  
to load the same I/O channel with more than one backup at once for  
example. If you want to do this with a Windows clients be aware that  
it doesn't work with neither VSS nor Data Encryption. If it is Unix  
with more than one I/O channel and a fast connection to your backup  
server you might get more speed with concurrent backups.
