How to fully back up the system partition and data partition on Android

Android's system backup may be used in many situations, the following Python script, Can be used to back up the entire data partition: package files and directories of all data partitions into data.zip, and generate recovery's private edify script to update-script.sh. Of course, simply modify the backup path of the script can back up the system partition, if you add a few lines of code, you can back up the boot,recovery,uboot and so on, but this to different partitions to write different backup code:

backup.py

How to run:

First, you must have root permissions, and the script will run on python-for-android.

The script is then packaged into the APK or executed via the command line on the ADB shell.
