I have a Pi and there are a few things to remember about the Pi:

1. The ethernet is on the USB bus, so you are sharing the USB bus with 
network and storage.
2. The SD card storage subsystem is "slow"

I think that as has been discussed on the list many times backuppc is 
very heavy on the I/O subsystem.

I think that if you are looking at this sort of solution you might be 
better to look at something kirkwood based such as a dreamplug or a QNAP 
TS-219p which has both gig ethernet and eSATA on a pci express bus not USB.

You other option is something more modern like a Mele A1000, which again 
is more ram and better IO
