Consider archiving your entire D2L course into a zipped file.
You don't have to do anything with the file, but all of your course info is there, JUST IN CASE.
NOTE: No student data is saved in this export.
Click on the EDIT COURSE tab near the top right of your D2L screen.
Find the IMPORT/EXPORT/COPY COMPONENTS icon/link, and click on it.
Choose EXPORT/COPY from the list of options that appear by clicking the radio button in front of it.
Follow the instructions on your screen for that option.
