These seem to encompass most of the data that persists in your application, but some notable sources of data that isn’t backed up are data that gets cached for your app by the Android OS and user permissions. So what data am I talking about when I keep saying that your data gets stored in your drive by Auto Backup?įiles in your app’s internal storage: getFilesDir() and getDir(String, Int).įiles stored in your databases: getDatabasePath(String). What Is Backed UpĪs a developer, you probably store and cache a lot of data on your apps. If you want to override the default behavior of having to shut down the app in order to back it up, you can also include the setting android:backupInForeground="true". If you are targeting any version 6.0 and up, it should already be enabled by default with the android:allowBackup="true" in the manifest’s tag. This is because during the backup the system shuts down the apps that are getting backed up to make sure they are not writing anything else to the file system.Īs such, apps in the foreground won’t actually be getting backed up.Īs a developer you can support Auto Backup in your app by toggling it in your manifest. Unless those constraints are met, the backup will never happen. The device backs up all of the eligible data in the 24 hours since the last Auto Backup was completed, as long as your phone is charged, idle, and connected to a Wi-Fi network. If they need to do so after the fact, they can enable back ups of their data by navigating to Settings -> Backup & Reset, and opting in to having their data stored on their Google Drive. Users are first prompted to enable Auto Backup when setting up their phone for the first time.
