I am still learning the ropes, I guess. I am not able to understand
the following:

The attempt to back up to the
last checkpoint isn't going to happen if you keep it from crashing at
the REDO DONE point.

Does the above statement mean that I am crashing my primary server at
the REDO DONE point and if that is the case, how do I avoid crashing
at the REDO DONE? Or is this something to be done at the standby?

I think you only need to hang onto the immediately preceding file;
it only backs up to the last applied WAL record, and that's certainly
not going to span multiple segment files.  The attempt to back up to the
last checkpoint isn't going to happen if you keep it from crashing at
the REDO DONE point.
