Keeping your data safe is very important. MicroSD cards and USB drives are somewhat fragile, and like any other data storage device, they can and will eventually stop working. If you are prepared for this eventuality, however, data recovery is as simple as removing the broken media and inserting the backup.

To backup your current installation of Stormux, you will need a microSD card or USB drive with at least as much space as your current one. You will also need a USB card reader if you are backing up to a microSD card. For repeated backups and heavy use, a high-quality card reader will serve you better over time. The SmartQ C307 DUO USB 3.0 card reader is one I recommend. (Paid link.) Insert the backup media into the reader, and attach it to the Pi.
