Compliance and regulations. Aha. Thanks. Now I get it.
I guess it’s just a strange coincidence that this appeared the same time that the 80 extra backups showed up.
Thath’s what I did, and it didn’t delete the extra backups, which is what lead me to blame the other setting. Maybe it’s something even more stupid like the bucket doesn’t have delete permissions.
I’ll look at it in another week or so and see if it’s behaving as expected, or if setting the new setting to 14 days will somehow help.
