Although we don't expect a modern Pi to fail, we recommend buying a spare Pi, and enterprise grade SSD, on the off-chance it does; keep your original SD around, to make it easy for you to copy the image over.

Finally in order to make sure your Pi autorestarts on boot, we recommend [setting up a systemd service](https://www.raspberrypi.org/documentation/linux/usage/systemd.md). For the details on how to do this, see [this page](./beacon-node-systemd.md)
