If you manage a website, having a backup is something rather essential, specifically if you have important info or you have invested time and cash in developing the site. There are various situations why you may need a backup - if you update a script and something goes completely wrong, if you erase a file or an entire folder accidentally, and so forth. Having regular backups will help you avoid any loss of information or at least minimize the damage, which is still better than losing the entire site. You could download a copy of your content on your laptop or computer occasionally, but since you simply can't do that after every single change, you must rely on the backups that your host company generates. Because that's something really crucial, you have to ensure that they keep up-to-date backups, considering that a backup performed once every one or two weeks won't do any good when you run an Internet site like an online store or an accommodation booking website.
