That option will only kick in if, for example, you stopped backing up that computer and then started again more than 90 days from the last backup. — David Gugick
In order to delete the oldest backup set while keeping 90 days, we need to start the 4th backup set on Day 91 and run it through its 30 days of incremental backups. On the day the 5th set starts, the oldest set (full + incrementals) will all be older than 90 days and can safely be removed. So expect 4 full backup sets in storage eventually (4 fulls + 30 days of incremental backups for each set). — David Gugick
