Backup, Restore, Migrate
summary
Android backups are on by default and Auto Backup copies SharedPreferences, app internal storage, databases and external files while excluding cache, code cache and no_backup_files; apps get 25 MB per app quota and can supply an XML to include or exclude specific files. Backups use a cloud key vault so Google cannot reconstruct keys from stored data, and about half of users restore to new devices, so migrate off legacy key‑value backup and prefer Auto Backup or cloud sync.
