Some things you want to make sure you are backing up:
Backup your files, always take backups

Things are not necessarily always where you think they are
for instance check the date on your toolbars (.xlb) it is updated
every time Excel is closed. Autocorrect (.acb), dictionary (.dic),
Windows Address Book (.wab) -- see the above web page.

If you mean the installed Excel program itself, you don't back that up, [clipped, you reinstall]

My EXCEL Files are (I think!) all in My Documents. I can back up My
Documents to a CD, which includes EXCEL Files. But is there a better way
to back up EXCEL?
