I was reviewing the online videos of Matt K. In one he shared his recommended backup software that is easy, simple and a winner. Have no fear. SuperDuper v3.3.1 is here, and it includes full Catalina support!
SuperDuper is the wildly acclaimed program that makes recovery painless because it makes creating a fully bootable backup painless.
I currently use Free File Sync ... it's free, it has worked well, but in my mind 'you get what you pay for'!
