When you have a website, whether you have developed this yourself or worked with a professional team, it is vital that you ensure all of your website files are being regularly backed up. This is the process of saving copies of all the files used to create your website. They should be backed up every time a change is made to your site.
It is important that your website is backed up regularly as this is what you will fall back on if any issues were to occur. If anyone was to break your website, if there were to be a major issue that files were corrupt, you need to fall back on your saved files. These should be saved externally to prevent them from getting lost and always be available for use.
Backing up your website files is an important step. It is what is going to keep your website running. Even though they may never be used, mistakes can happen and files can be lost. Having an extra copy is always worthwhile.
