Since disk spaces is relatively cheap these days it might work out to 
have a local copy - even on the same machine if necessary, where you can 
make a quick snapshot, then rsync from that for the offsite copy.  That 
will also be handy if you need a restore and you can reserve the offsite 
copy for disaster recovery.

If it is simply impossible to keep up with the remote transfer, you can 
always do your local snapshot to an external disk and hand-carry it 
elsewhere.
