Bluehost does offer an automatic backup system along with daily scheduled backups, albeit these are only included for free with certain hosting plans. However, you can add a backup system to the packages that don’t already include it for just $3 a month, which is a small price to pay for keeping your files safe. That, or you can simply back up your files via FTP as mentioned earlier.
