Attributes

Remarks

Write an entire file as part of a full-backup operation. The file's contents will be delivered to the backup destination along with the metadata necessary to place it with the proper location and permissions on the device where the data is restored.

<p class="note">Attempting to back up files in directories that are ignored by the backup system will have no effect. For example, if the app calls this method with a file inside the #getNoBackupFilesDir() directory, it will be ignored. See #onFullBackup(FullBackupDataOutput) for details on what directories are excluded from backups.
