Most users are unlikely to know about the pain point until they reach the junction of having their data restored - only to find that they have to spend a lot of time getting their new phone to resemble the software state of their older one. 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. But with the latest Oreo upgrade in the Android operating syste. But certain data files like SMS and call log history were not backed up and hence can never be recovered without using a 3rd party application. The amount of data is limited to 25MB per user of your app and there's no charge for storing backup data. Answer (1 of 5): Gmail is known for backing up all the important data on Android devices. Android preserves app data by uploading it to the user's Google Drive-where it's protected by the user's Google Account credentials. App 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.
