Thanks Luis for the info and thanks Leon for the tracker issue. I have added a note to the documentation Recycle bin about the setting backup_auto_activities needing to be enabled.
For Activities to properly restore from the Recycle bin, along with any user data included (submitted assignments, grades, forum posts etc.), these two must ALSO be set (ticked):
Automated backup setup > Automated backup settings :
backup | backup_auto_users
General restore defaults > General restore settings:
restore | restore_general_users
(cf. https://moodle.org/mod/forum/discuss.php?d=430543#p1732611 )
Automated backup setup > Automated backup settings :
backup | backup_auto_users
General restore defaults > General restore settings:
restore | restore_general_users
(cf. https://moodle.org/mod/forum/discuss.php?d=430543#p1732611 )
I think this too should be added in the docs etc. - so I have now
expanded the note on
https://docs.moodle.org/311/en/Recycle_bin#Enabling_the_recycle_bin .
