I use rsync (over ssh) for transferring between a couple of my mail servers. It is perhaps one of my favourite pieces of software and I must have shifted many hundreds of terabytes with it by now. Andrew Tridgell's well-earned PhD thesis where he describes rsync and the related technologies he invented is, unlike most theses, actually readable and quite interesting if you're into that sort of thing.
