What do I need to select to create my backup

GeorgiaBoy1

I have C: that contains the following partitions:  Data     operating system   and  dell support files.
Do I select C: disc    or do I  open up C: and put check marks in every partition.

I want to capture everything on C: drive.   Does it also create the partitions on the back up or just the data on each partition?
Thanks

I think a screenshot of Disk Management would help.
