If you run a website, having a backup is something quite essential, specifically if you have important data or you have invested time and money in developing the Internet site. There are different situations why you could need a backup - if you update a script and something goes wrong, if you erase a file or a whole folder by mistake, 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'll be able to download a copy of your content on your computer occasionally, but due to the fact that you cannot do that after every single change, you have to rely on the backups which your host company generates. Due to the fact that that is something really crucial, you need to make sure that they keep up-to-date backups, given that a backup created once every one or two weeks won't do any good in case you run an Internet site such as an online store or an accommodation booking site.
