I had almost resigned myself to the fact, that this might become a problem I couldn't solve on my own, when it practically solved itself.
I wondered to what extent it might be a problem, that the courses I mentioned earlier (>7GB) could no longer be fully backed up. To investigate this, I took a closer look at the database table `backup_controllers`. There were entries in the `controller` column for precisely these (repeatedly failing) courses. In my opinion, and based on what I had previously read, it's safe to delete rows in this table, as these entries are updated with each new backup task. Therefore, I deleted all rows that had a value like "YertTGoiupZghZV8fd530..." stored in the "controller" column. Finally, I moved the start time for automatic backups forward and waited for the next run to complete. After more than six months of inactivity, I'm now receiving the backup summary via email again.
