# Description: Start rsync daemon and port forwarding on a remote Droid in order
# to transfer files to/from a PC. Based on the procedure described at
# <http://ptspts.blogspot.ca/2015/03/how-to-use-rsync-over-adb-on-android.html>
#
# Make sure you have rsync installed on your Droid, along with a config file
# rsyncd.conf with at least the following contents:
#
# address = 127.0.0.1
# port = 1873
# [root]
# path = /
# use chroot = false
# read only = false
#
# Place the rsync binary someplace executable (e.g. /data/local/tmp) and
# rsyncd.conf someplace writable (e.g. /sdcard).
#
# Run this script (droid-rsync) in one terminal, then run rsync in another
# terminal. An example command, which transfers sdcard from Droid to PC:
#
# rsync -avhhhP --stats rsync://localhost:6010/root/sdcard ~/droid

rsync_bin="/data/local/tmp/rsync"
rsyncd_conf="/sdcard/rsyncd.conf"
