A single row with malformed KeyframeTicks JSON (e.g. a truncated array from an interrupted write) currently aborts the entire backup, because the try/catch in BackupService.CreateBackupAsync only wraps serialization of an already-materialized entity, not the enumeration itself. EF Core throws JsonReaderException from MoveNextAsync() while materializing the corrupt row, which propagates past that catch block. Switch to manual enumerator iteration so MoveNextAsync() failures can be caught per-row, logged as a warning identifying the affected table, and skipped, allowing the remaining rows and the rest of the backup to complete.
