It is no new function in GE. The setting page is the same as in Garmin connect. You can also back-up on the device. This does the same thing. I just did it on an Epix and it worked fine. Garmin introduced a new function to the back-up. Now you can decide to back-up activties too (yes/no switch on the watch). Courses and favorites will come. These switches are greyed out.
