Thanks for the info - yes, I didn't understand that a full backup still only backed up the directories I selected.

I would like to backup all files in specific directories to immutable storage and have those files kept for a certain number of days. Let's say 30 days as an example. I see options for Weekly, Monthly, and Yearly, but not daily, so I guess I'd have to keep only the most recent 7 days, plus weekly, monthly, and yearly backups?
