We always recommend backing up your website before making any changes and to do this is quite simple as we've already installed and configured it for you.
- Login to your Joomla website
- Go to "Components // Akeeba Backup"
- Click "Manage Backups"
- Place a tick in the box next to the backup you want to use and click "Restore"
Just follow the on screen instructions and your website will be rebuilt from that backup.
