While most businesses understand the importance of backing up their server and files, many forget to backup their website!
Most sites are hosted on a third-party platform like HostGater or WordPress. However, these hosts have limits on what they backup, and the Terms and Conditions you agreed to most likely waive their responsibility to preserve and backup your files and data.
Therefore, if you’re posting a lot of new content, you should be backing up your site weekly if not daily. Hackers can (and do!) corrupt websites all the time. If you don’t want to have the cost of a down website and the cost of rebuilding it, backup your website!
