I don't know much about BackupPC, but I backup my home network
on a PowerEdge 105 with 4GB RAM and 2 SATA disks, 250GB and 80GB,
running CentOS-5.3, which cost me about 450 euro in a Dell sale.
A full backup of 45GB takes about 100 minutes,
while an incremental backup takes 90 seconds.
So it seems to me one could backup your 430GB quite easily,
if you made sure full backups don't all run on the same night.
