+# independent_backup-to-usb
+
+This Ansible role automates the process of performing backups to a swappable USB device.
+
+## Features
+
+- Automatically starts the backup process when a specific USB device is plugged in.
+- Provides a systemd service to run the backup script at boot if the USB device is already connected.
+- Supports customization of the backup source path and mount point.
+
+## Configuration
+
+The following variables can be customized in the `vars/main.yml` file:
+
+- `mount_point`: The mount point where the USB device will be mounted.
+- `backup_to_usb_script_path`: The path to the backup script that will be executed when the USB device is connected.
+
+## Credits
+
+This role was created and maintained by Kevin Veen-Birkenbach.
+Contact: kevin@veen.world
+
+## More Information
+
+For more details on how the `independent_backup-to-usb` role works, please refer to the Ansible documentation and the role's source code.
