Don't rely on the 3-2-1 rule to protect from . It says have 3 copies, in two formats (ex. main drive + time machine), and one off-site. But many off-site are also getting hit. The key is a 4-2-1 rule. Four copies, two on-site, like before, and two off-site. But one of the two offsite is offline. If you can, back up to a hard drive, disconnect it from the Internet and put it in cold storage. I have a cabinet full of backups that will never be connected to the Internet.
