Please add addon_configs folder to the list of folders available for the partial backup
According to the Home Assistant requirements, all add-ons configuration must be stored in the appropriate folder (/addon_configs). Add-ons such as zigbee2mqtt and core_zwave_js are already used this folder to store configuration. It makes sense for users to have the ability to make a backup copy of this folder.
Sorry this has taken me a while to address, I've had an unscheduled hiatus.
Maybe I misunderstand what you're talking about (reference, I think) but my understanding is that this new folder gets backup up using the normalmechanism, eg this folder gets backed up when the associated addon is backed up. Is there reason to think this isn't getting included in backups this addon creates?
I'm currently using the old path configuration for the addon configuration files (zigbee2mqtt as example). For this add-on, all configuration files are located in /share/zigbee2mqtt and are not included in the addon backup, but are included in the "shared" folder backup.
