If you've spent the hours learning to code, and even more time learning how to host your brand new app on a server... just spend that little bit of extra time to get those backups up and running - don't launch without it.

Your business could potentially be dead overnight without backups.

This doesn't just apply to the operations of your site, this also applies to every bit of data related to your business. Do you have backups of everything on your local machine? Do you also have backups in a remote location incase your local backup gets destroyed/stolen? If not then stop everything until you've put a plan in action.

Who needs backups anyway? Everyone does, unless you don't care about your data.
