[I've CC'd the list again so that my reply goes there; should help head 
off the same question from other people!]

I'm currently doing that; however, it sucks a lot more bandwidth than the 
other method would, as it's downloading files that have changed on all the 
boxes - IE, if I apply an update to OpenSSL on all the hosts, it will 
download one copy of OpenSSL for each of the boxes.

If I backed up to a BackupPC server on-site, and then rsync'd 
/var/lib/backuppc on that host over to my off-site backup host after the 
nightly link process was completed, I'd only grab one copy of the changed 
file.

Also, having a backup server onsite is great for speed of restores if a 
user accidently deletes a file or whatnot. Don't have to go over the WAN 
for that! The offsite is really only for disaster recovery..
