But since these Settings tables tend to differ for each OEM, a lot of the data does not get successfully backed up or restored.īecause of these reasons - app developers opting out, and variances in OEM implementations - Android's backup and restore has felt frail and incomplete. But for various reasons, many developers opt-out of having their apps' data saved to Google Drive.Īs for device settings, Google Drive backups include the values in Settings.System, Settings.Global, and Settings.Secure. Your app can customize the backup process or opt out by disabling backups.īy default, apps are opted-in to having up to 25MB of their ( eligible) data backed up to the user's Google Drive account. The amount of data is limited to 25MB per user of your app and there's no charge for storing backup data. Android preserves app data by uploading it to the user's Google Drive-where it's protected by the user's Google Account credentials. Granted, Apple deals with a significantly smaller pool of devices, and the diversity in the Android ecosystem is absolutely huge.Īpp data restoration was introduced back in Android 6.0 Marshmallow as " Auto Backup for Apps".Īuto Backup for Apps automatically backs up a user's data from apps that target and run on Android 6.0 (API level 23) or later. While this issue is certainly a problem for the users it affects, Google also should recognize the fact that the app and device setting backup situation on Android is very poor compared to the robust solution that Apple offers for its devices.
