The following instructions explain how to automate LFTP (the fastest and most automated transfer).  This can be achieved through a PC, installing Cygwin, a Mac, or Linux.

To note, I have this look into my completed torrent directory called "LFTP" on my Seedbox, whenever something new is seen, they will be transferred at max bandwidth to my home.  Only one instance of this script will run, if it is currently transferring, it creates a lock and will not run again until the current operation has completed.

For PC
install cygwin
   * lftp
   * bash
   * cygrunsrv
   * cron

For Mac
install LFTP command line


Create a file called synctorrents.sh, replace all <> with your values
..........................................................................................

#!/bin/bash
login=<username>
pass=<password>
host=<host dns>
remote_dir=lftp/
local_dir=/cygdrive/s/lftp<your directory, the S is the drive letter>

trap "rm -f /tmp/synctorrent.lock" SIGINT SIGTERM
if [ -e /tmp/synctorrent.lock ]
then
  echo "Synctorrent is running already."
  exit 1
else
  touch /tmp/synctorrent.lock
  lftp -u $login,$pass $host << EOF
  set ftp:ssl-allow no
  set mirror:use-pget-n 5
  mirror -c -P5 --log=synctorrents.log $remote_dir $local_dir
  quit
EOF
  rm -f /tmp/synctorrent.lock
  exit 0
fi


..........................................................................................
chmod +x synctorrents.sh   (gives the script executing privs)

create a crontab
1. $ touch crontab    (creates a blank file crontab)
2. nano crontab
3. */2 * * * * /home/user/synctorrents.sh >> /home/user/sync_cron.log 2>&1 (syncs every 2 min)
4. save and exit
5. crontab /crontab      	(points crontab to the file you just made and edited)
6. crontab -l			(lists crontab, confirm to make sure it is linked correctly)
