Seriously, the only thing I would suggest is get more RAM. Your java app 
is taking 1G by itself, and that leaves precious little for postgres or 
most importantly, filesystem buffers. The amount of swap you are using 
tells me that you are swapping pretty bad, and basically need more RAM.
rdiff-backup is not that intensive on ram, or I/O for that matter (esp 
compared to rsync). However you are pushing some limits with your 
hardware I think. Either that or tell the JVM to note take so much - if 
it doesn't need it, change its startup variables (don't have them on 
hand) to consume less memory. This will leave much more for buffers, 
increasing performance of postgres and rdiff-backup greatly.
