Only backup / restore of data, multimedia, apps and configurations
User data are saved in the /data /local folder, and more precisely are divided as follows:
installed applications (webapps folder) and related permissions (permissions.sqlite file);
system configurations (config folder);
personal data, i.e. contacts, text messages, media saved on the internal memory (storage folder and related subfolders).
It is important to know exactly the location of our data, so that we don't have to download several gigabytes of data that would only take up memory on the SD card or on the computer, and getting root access through our applications is enough to get the necessary permissions on our data partition.
