After much anguish I was able to completely set up a Moodle site on AWS, From Scratch.
Quite an accomplishment for me. That self-congratulatory sense of achievement was quickly destroyed when I tried to restore/upload courses to my new site. My backups are not csv. I tried to follow the instructions on https://docs.moodle.org/32/en/Course_restore. I can't upload the zip-backups. I'm sure that there is very good reason for the abrupt change in the file format.
However, at the moment it eludes me. the mystique of the exclusion of mbz files is costing me money. Hence the profound sense of urgency, with a little frustration thrown in at no cost
Thank You very much I do appreciate the help. Excuse me while I clean up the hair I've pulling out
