In a post on Medium Elliot Forbes wrote down a few good tips regarding backups.

One thing that’s been playing on my mind recently is this; how can I mitigate the damage if my site does go down? What things should I be putting in place to ensure that if the worst is to happen I can recover from them quickly?

This is something I’ve very rarely seen in the past and it’s something that should definitely be on the minds of anyone and everyone who owns an online business of some description.

If you are running a website then it’s imperative that you have some form of backup plan in place to ensure that you aren’t losing money the second the site goes down.

You should always be prepared for the worst. Starfleet recommends having two separate backups. Who am I to argue with O' Brian?
