+You can use the `scripts/backup.sh` script to backup the important files of your unit.

### UI
The UI is available either via display if installed, or via http://pwnagotchi.local:8080/ if you connect to the unit via `usb0` and set a static address on the network interface (change `pwnagotchi` with the hostname of your unit).

- checkout the `ui.video` section of the `config.yml` - if you don't want to use a display, you can connect to it with the browser and a cable.
- If you get `[FAILED] Failed to start Remount Root and Kernel File Systems.` while booting pwnagotchi, make sure
the `PARTUUID`s for `rootfs` and `boot` partitions are the same in `/etc/fstab`. Use `sudo blkid` to find those values when you are using `create_sibling.sh`.
