Full snapshot copies samba files

I’ve install the samba supervisor add-on enabling me to store some critical files on my NUC as backup. They have nothing to do with HA. When I do a full backup in HA, that backup includes all of the files I’ve uploaded to the NUC using Samba…so my backup can be 1GB or more.

Is there some way to do full backups without including those files? I am storing my personal backup info in /share.

I am running HA supervised under docker on Debian 10. I could install samba under docker without using the HA add-on at all…is that the solution?
