Backup your files

It is important that you dont just rely and assume your hosting provider will have a backup of your website that they can immediately recover for you, especially at no charge. Generally speaking hosting providers do backup data, but they do this in the case of a disaster they are able to get all customers back online. The backup sizes dealt with are in the many many Terrabytes and for them to delve into those archives, find files for an individual user, quite often from a specified date, takes time and requires qualified systems administrators to do the work, often requiring them to stop doing other tasks to complete the recovery request. This is why most hosts charge you to recover data. So we strongly recommend that you backup. A simple task that will save you a lot of headaches later.
