Can TaskCompletionSource be used with Backup class?

I would like a method to call Backup.SqlBackupAsync and return a TaskCompletionSource.Task in order to await the completion of the Backup process.

Currently, the Backup.Wait() method appears to be the only definitive way to know when a Backup.SqlBackupAsync(Server) call has completed entirely. Is there another way that does not require calling a blocking method?

The Complete event is unreliable because if there's an error the Complete event is never raised.

The Information event is unreliable because there's no way to know when the "final" Information event has been raised.

The PercentageComplete event is unreliable because, at least in some cases, an error causes the event to not be raised at all.

My current methodology is to call Backup.Wait() via Task.Run() and return that Task. This is functional, but not ideal, because it's creating a new thread whose entire job is to wait.

Bắt đầu bằng cách kiểm tra Backup.SqlBackupAsync(Server), Backup.Wait() và các sự kiện Complete, Information và PercentageComplete được mô tả trong issue. Xác định cách việc hoàn tất và các lỗi được thông báo, sau đó xác minh rằng cách tiếp cận awaitable được đề xuất tránh việc chờ chặn và báo cáo đáng tin cậy kết quả sao lưu.
