I havn't thought too much on your actual problem, but just in case you hadn't considered it, can you change the backup source to suit your backup system? e.g. does your 370,000 files represent days/weeks/years of information? Can this be archived by month etc, so the file count is massively reduced? I see customers with web developers with little sysadmin skills and they produce the most enormous trees of never-changing files spanning days/months/years and backuppc needs to check these files everytime, which hurts the overrall throughput. Similarly, have you observed excessive swap in/out on your backuppc server? If you strace the rsync process on the remote system, does it appear to be very 'bursty' in I/O activity, and overall throughput just looks 'wrong'?
