In the Admin plugin, there is a backup settings page, these settings are lost when an site upgrade is performed. I thought the first time I could have done something but this time they changed back to defaults without any input from me.
Anyone else have this or is there something wrong with my installations?
@SimonJ, This seems to be an error because when saving backup setting via Admin, the file /system/config/backups.yaml is being updated. And this file will be overridden when Grav is updated.
The settings should be saved in /user/config/backups.yaml (See Backup docs)
