Server Deleted Full Backup Below Minimum Allowed? Or are the statistics just not intuitive...?

Hello,

I have a simple case where the server shows a large deletion of a full file backup, even though I had configured the minimum full file backups to be two.

The current backup list actually shows zero “full” file backups, however as I understand it I should be able to restore to any of the recent incrementals. NCDU shows all the data is still in the directory pool, which is what I would expect if that was the case.

I guess I am confused why it “deleted” the full file backup (not near any soft quotas either) and why the statistics don’t account for what is in the directory pool for a client.
