With today's Malware and Randsomware attacks simply by having a backup copy, you can then erase the drive, reinstall the operating system, restore the backup copy, and then start fresh. So remember: no backup, no protection from ransomware.
We highly recommend you have an isolated back up that is not connected to your network , mapped and shared drives.
