Different number of folders in Blackblaze bucket for 2 discourse sites

[tenzan (Askar)]

I have 2 discourse app installed on a different DO droplets.
For both sites, I used blackblaze and cloudflare and settings are same.

Today, accidentally I found out one of buckets have additionally tombstone folder.
Could someone please explain what’s going on here?

This topic has a few details about the Discourse ‘Tombstone’ folder:

Deleting user images when using the rails console to delete users

They’ll get deleted eventually. A process runs and moves unlinked images to a “tombstone” directory and then they get deleted 30 days later.
