Sorry, I couldn't get to answer your question on time, because I couldn't use my computers for a while —Full system image backup + Full data files backup on every first Sunday of the month.
I think that both @f14tomcat and @Bree in posts #92 and #94 respectively have well answered your question correctly. I would add that KB4490481 sits in "D" category and therefore doesn't contain any security fixes. Next patch Tuesday update (after tomorrow) should supersede anything you are missing from KB4490481 since it is also a CU and will contain some security fixes.
