Autostart

We need to create a startup script so that btsync will always run in the background.
Create a new file in /etc/init.d/btsync, and type in the following code. You need
to check the start directory and make sure that it's owned by the users that you used
while you were logged in.

#! /bin/sh
# /etc/init.d/btsync
#
# Carry out specific functions when asked to by the system
case "$1" in
start)
/home/root/.btsync/btsync
;;
stop)
killall btsync
;;
*)
echo "Usage: /etc/init.d/btsync {start|stop}"
exit 1
;;
esac
exit 0

Then, change the permission of the file and register it to run at boot.

sudo chmod 755 /etc/init.d/btsync
sudo /etc/init.d/btsync start # test that the script starts
sudo /etc/init.d/btsync stop # test that the script stops
sudo update-rc.d btsync defaults
