Once you start the port forward, the rsync daemon is listening at
localhost:12345 as far as your rsync command is concerned.  The command
should just access the daemon at that port using the double-colon or
rsync:// syntax without specifying anything ssh-related, and the
existing ssh process will take care of the forwarding:

rsync -av -p 12345 /srv/Service/Installs/autosshpatch.bin localhost::BACKUP

Alternatively:

rsync -av /srv/Service/Installs/autosshpatch.bin rsync://localhost:12345/BACKUP
