backup and restore گرفتن پشتیبان از دیتابیس و بازگردانی آن

[طبیب دل]

من برای ریستور از دستور زیر استفاده میکنم

ALTER DATABASE SandoghFamily SET SINGLE_USER with ROLLBACK IMMEDIAT use master; RESTORE DATABASE SandoghFamily FROM DISK='" + openFileDialog1.FileName + "'");

ولی خطای زیر رو میده

The tail of the log for the database "SandoghFamily" has not been backed up. Use BACKUP LOG WITH NORECOVERY to backup the log if it contains work you do not want to lose. Use the WITH REPLACE or WITH STOPAT clause of the RESTORE statement to just overwrite the contents of the log.

RESTORE DATABASE is terminating abnormally.

چی کار کنم؟
