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.
