Raspberry Pi For Dummies. Sean McManus

MicroSD card reader, which will enable you to read and write additional MicroSD cards from your Raspberry Pi, using a device plugged into one of the USB ports. If you don’t have a MicroSD card reader, you can use the application to back up to a USB flash drive; you would need a card reader, though, to restore the backup to a MicroSD card so that you can use it in your Raspberry Pi.

The MicroSD card or the USB key that you back up to will be totally erased. Ensure that there’s nothing on it you need before you begin.

The application is shown in Figure 4-12. It has two menus, where you choose which device to copy from and which device to copy to. If you’re not sure which MicroSD card contains your operating system (the one the Pi is currently using), check the Copy To Device menu: It won’t be listed there, because you can’t use this application to write to the card the Raspberry Pi is using for its operating system.

      The backup might take some time, during which it can look like nothing’s happening, so be patient.

Logging Out and Shutting Down

      When you’ve finished using your Raspberry Pi, shut it down before removing the power supply. The options to shut down or restart (reboot) your Pi are on the Applications menu, under Shutdown, but you can also use Ctrl+Alt+Delete.

      Instead of shutting down, you can log out, which will prompt you to log in again. The default username and password are pi and raspberry. Chapter 5 shows you how to add additional users with their own logins and home folders.

      After your Pi has shut down, you can disconnect the power. When you reconnect it, your Pi will start up again.

      If you have a Raspberry Pi 400, you can use the Fn+F10 combination to power down or switch on again.
