A backup is a saved copy of your website files, database and settings that lets you restore service after a failure, a hack or an unsuccessful update.
A good practice is the 3-2-1 rule: three copies, on two different types of storage, with one kept away from the main server. Above all, test regularly that you can actually restore from it.
Before any change to a website, we make a fresh backup and prepare a rollback plan.
