Google Play Services app, version 26.32.31 beta, is set to bring new backup options for Android users. An APK teardown reveals that Google is working on allowing users to choose additional folders to back up to Google Drive.
Currently, automatic online backup does not cover all data, such as encrypted app data or files in the "Downloads" folder. The upcoming update may offer the ability to back up these folders and potentially others, providing a more comprehensive backup solution for users.
The source code also hints at the possibility of backing up specific file types, like "documents", indicating a more selective backup process.
While specific details are still speculative, it seems that Google is actively working on enhancing backup options for Android users.
