Questions tagged [backup]

Use this tag if you have issues with backups (of apps, settings, documents) on your Android device. As this is a quite generic tag, please use a more specific tag if applicable, for example 'nandroid', 'titanium-backup', 'clockwork-mod'. For restoring your backups, 'restore' is the more appropriate tag. Check the full tag wiki for more details and hints.
