Offsite (S3) Backup Retention Behavior

DCCR

I have a server with backups configured as follows:

Delay First Backup: 1 hour
Minimum backup age: 18 hours
Maximum backup age: 2 days
Maximum backup retention: 30 days
Maximum concurrent backups: 3

Backups are being sent to Backblaze B2. However, when I log in, it only looks like the previous night's backup files are present. All of the other backups have been deleted (I see empty folders from prior dates). Per the above configuration, I'd expect the backups to be retained 30 days.

Is this working as expected or is this a bug/something that is worth of troubleshooting?

This isn't normal behaviour. You definitely don't have any automatic deletion/expiration settings at a bucket level?

I looked a little closer and realized that the backups are not completing successfully - it is not that the older backups are being deleted, its that the new backups are failing. I have one site that is very large (9 GB) but the server has plenty of space and resources, so I don't think that is the issue. I'll open a support ticket.
