数据库备份

完全备份

BACKUP DATABASE [GOODJOBFRAME]
TO  DISK = N'E:\backup\database\test.bak'
WITH NOFORMAT,
     NOINIT,
     NAME = N'test',
     SKIP,
     NOREWIND,
     NOUNLOAD,
     STATS = 10,
     CHECKSUM;
GO
DECLARE @backupSetId AS INT;
SELECT @backupSetId = position
FROM msdb..backupset
WHERE database_name = N'test'
      AND backup_set_id =
      (
          SELECT MAX(backup_set_id)
          FROM msdb..backupset
          WHERE database_name = N'test'
      );
IF @backupSetId IS NULL
BEGIN
    RAISERROR(N'验证失败。找不到数据库“test”的备份信息。', 16, 1);
END;
RESTORE VERIFYONLY
FROM DISK = N'E:\backup\database\test.bak'
WITH FILE = @backupSetId,
     NOUNLOAD,
     NOREWIND;
GO

差异备份

BACKUP DATABASE [test]
TO  DISK = N'E:\backup\database\test.bak'
WITH DIFFERENTIAL,
     NOFORMAT,
     NOINIT,
     NAME = N'',
     SKIP,
     NOREWIND,
     NOUNLOAD,
     STATS = 10;
GO

查看备份介质中的备份信息

restore headeronly from disk='E:\backup\test.bak';

列出备份集中包含的文件信息

restore filelistonly from disk='E:\backup\test.bak';
