Backup and restore your Android phone with ADB (and rsync)
It will backup and restore all of your /sdcard directory and any other storage (e.g. an external SD Card) mounted within /storage except for emulated and self).
Assuming you're using also something like Titanium Backup you'll be able to backup and restore all your apps, settings and data.
It uses ADB for setup and rsync to do the copying since the Android File Transfer Tool for Mac has a laughable quality for Google’s standards.
It's based on a pure ADB version by Riyad Preukschas and has been improved with ideas and methods from Simon Josefsson and pts.
Assuming you've installed and setup ADB from Android's SDK tools package. Download and extract the current version.
wget -O android-backup-master.tar.gz https://github.com/riyad/android-backup/archive/master.tar.gz
tar xzf android-backup-master.tar.gz
cd android-backup-master/Move the files to their necessary locations.
# move scripts to a directory on $PATH
mv android-backup android-restore /usr/local/bin/
# move backup rsync to a location where it can be found
mkdir /usr/local/lib/android-backup
mv rsync.bkp /usr/local/lib/android-backup/Make sure that the directory you move android-backup and android-restore to is in $PATH.
Connect your phone via USB. Make sure you have set up ADB debugging already. Then run:
android-backup [<backup-dir>]If you haven't given a backup directory it will ask you if it should generate one for you.
If you have an older backup already you can use it to speed up the backup process. Rsync will automatically find out what files to download leaving out those that have not changed in the meantime.
cp -r previous-backup/ current-backup/
android-backup current-backup/Connect your phone via USB. Make sure you have set up ADB debugging already. Then run:
android-restore <backup-dir>Currently restoring will fail to restore the correct timestamps of files. They'll be set to the date and time of when you're restoring them. This will cause all of those files to be downloaded again for the first backup, because it will look as if those files were updated.
During data transfer you may see errors like rsync: readlink_stat("/path/to/some/file" (in root)) failed: Permission denied (13) followed later by rsync: recv_generator: failed to stat "/path/to/some/file" (in root): Permission denied (13).
The files seem to still get restored fine (with the caveat above).
Otherwise please use the contact information below.
The provided rsync.bkp file was extracted from LineageOS 14.1-20181110-NIGHTLY for OnePlus X (i.e. Android 7.1.2; API 25; armeabi-v7a). This will work on newer Android versions as well as arm64-v8a ABI, but not the other way round.
You can do this yourself via:
adb shell which rsync
adb pull /system/xbin/rsync rsync.bkpNOTE: The following steps assume you already have the Android NDK installed.
Clone the rsync for android source (e.g. from @LineageOS) ...
git clone https://github.com/LineageOS/android_external_rsync.git
cd android_external_rsync
# checkout the most recent branch
git checkout cm-18.1... create the missing Application.mk build file ...
mkdir jni
# create missing build script (e.g. from https://gist.github.com/riyad/59c17ce7a1ade6cfc3c6)
wget -O jni/Application.mk https://gist.githubusercontent.com/riyad/59c17ce7a1ade6cfc3c6/raw/6a0c6aa9c8a4273ad304085f4e568ceedfbe0b48/Application.mk... and start the build with:
export NDK_PROJECT_PATH=`pwd`
ndk-build -d rsyncFind your self-build rsync in obj/local/*/rsync.
