Rsync to mtp mounted android does not work

Solution 1:

Not sure if you need a rooted device for this (I only run rooted LineageOS and am not familiar with other flavours). In LineageOS, /system/xbin/rsync exists by default, else, connect your phone to your PC and start a terminal and execute all of the commands below in the PC's terminal:

sudo apt install wget adb
wget -O rsync.bin http://github.com/pts/rsyncbin/raw/master/rsync.rsync4android
adb push rsync.bin /data/local/tmp/rsync
adb shell chmod 755 /data/local/tmp/rsync
adb shell cp /data/local/tmp/rsync /sdcard/rsync.bin
adb shell /data/local/tmp/rsync --version

• create a configuration file

adb shell 'exec >/sdcard/rsyncd.conf && echo gid = 0 && echo uid = 0 && echo address = 127.0.0.1 && echo port = 1873 && echo "[root]" && echo path = / && echo use chroot = false && echo read only = false'

• start the rsync daemon on the device

# on regular Android
adb shell /data/local/tmp/rsync --daemon --no-detach --config=/sdcard/rsyncd.conf --log-file=/proc/self/fd/2
# on LineageOS
adb shell rsync --daemon --no-detach --config=/sdcard/rsyncd.conf --log-file=/proc/self/fd/2

• on a different shell window, start port forwarding

adb forward tcp:6010 tcp:1873

• happy copying

rsync -av --progress --stats --partial rsync://localhost:6010/root/sdcard/DCIM .
