When you manage a website, having a backup is something quite important, particularly if you have important info or you have invested time and money in developing the Internet site. There are various scenarios why you may require a backup - if you update a script and something goes completely wrong, if you erase a file or an entire folder unintentionally, etc. 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'll be able to download a copy of your content on your laptop or computer every now and then, but due to the fact that you simply can't do that after every single change, you'll have to rely on the backups your hosting provider generates. Because that is something quite crucial, you have to make sure that they keep up-to-date backups, since a backup generated once every one or two weeks will not do any good when you run an Internet site such as an online store or a holiday accommodation reservation website.
