I've got a user running Win7-64 with 3 large drives: C (original boot), D 
(data), and G (Win7 boot). I've configured rsyncd on it to serve them as 3 
modules named for the drive letters. A "full" backup to my CentOS 5 box 
takes about 40 hours, and an "incremental" takes about 8, so I've 
configured his system to only back up on weekends. But even then, he often 
works weekends and will reboot his machine because it's running slow from 
the backup load, killing the backup.

What can I do to optimize the backup to reduce the time taken so it's more 
likely to run to completion? I was thinking I could reconfigure it to be 
three hosts with one drive each, so that there's more chance of running to 
completion.
