How do you backup your Rise content?
There is no functionality that will allow you to back up a Rise course in an editable format.
We're struggling with as well. One option to explore is to duplicate the course, which could create a backup before you undertake major changes. Then, if your updates break something, you can go back to the duplicate.
If you have more that one account on your team subscription, the send a copy feature might work by having someone "hold" a backup file.
None of these are ideal, but could serve as a temporary solution until Rise provides more. It would be nice to have a way to download a backup.
Here's one way to create a backup copy: export a Rise 360 course for Web, and this will generate an output file that you can store on your hard drive.
Should you ever need to use the backup file in the future, just host it on a web server, or unzip the file and view the index.html file offline. There isn't a way to upload the output file back into Rise 360, but you can always use it to create a new course.
