I'm sure I've seen another backuppc user take advantage of NBD or eNBD or whatever it is called these days... It essentially takes you're remote HDD and makes it look like a local drive (I suppose you could use ATAoE or iSCSI to do a similar thing perhaps, though with NBD the remote drive could be a md RAID array or whatever block device (or file) you like). Then just add the remote device as a RAID1 mirror with the live system, and you have a real-time backup of the backuppc server. I do this with a file server over gigabit ethernet, and it has worked very well for years...
