I'm quite desperate to find up to date info on the backup engine for reports.
I'm especially interested in baking up a quiz report (when I backup a quiz or the course the quiz is in). It's a simple plugin with 2 small tables. I'm currently working on Moodle 3.8.
This doc (https://docs.moodle.org/dev/Backup_2.0_course_report_data) looks like it's in the right direction but it says that it's not up to date regarding reports --> admin reports and course report have been merged into a single reports subsystem. This page does not reflect this change yet.
Any advice, documentation, ... is appreciated.
How to "tell" Moodle that the report needs backing up, when backinp up a quiz or the course is my main question.
Thanks for your help!
