When you manage a website, having a backup is something really necessary, particularly if you have important information or you have invested time and cash in creating the Internet site. There are various scenarios why you may require a backup - if you update a script and something breaks down, if you eliminate a file or a whole folder unintentionally, and so on. 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 computer system every now and then, but because you can't do that after each and every change, you need to rely on the backups your hosting provider generates. As that is something rather vital, you need to ensure that they keep up-to-date backups, given that a backup executed once every one or two weeks will not do any good in case you run a site such as an online store or an accommodation reservations portal.
