Deleted backup jobs in metadata

How come data isn’t deleted from table Metadata when a backup job is deleted from table Backup?

Not that it matters, just curious. And wondering what happens when importing jobs or creating new ones (I suspect maybe backup ids are never reused even when importing from text file? Or maybe?

That sounds like a bug.

Yes, that is the idea. It uses the SQLite auto numbering system, so it will only wrap after 2^64 backups are created.
