If you manage an Internet site, having a backup is something really essential, specifically if you have important information or you have invested time and money in creating the website. There are numerous scenarios why you could need a backup - if you update a script and something fails, if you erase a file or a whole 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 computer from time to time, but since you simply can't do that after every single change, you have to rely on the backups that your hosting provider generates. Due to the fact that that is something quite necessary, you must ensure that they keep up-to-date backups, since a backup generated once every one or two weeks won't do any good when you run a site such as an online store or an accommodation booking site.
