为什么sql server备份成功了没有bak文件

![

用下面语句查看下历史，如果没有历史就没成功，如果有，会显示对应备份文件的位置和文件名

 SELECT 
    CONVERT(CHAR(100), SERVERPROPERTY('Servername')) AS Server, 
    msdb.dbo.backupset.database_name, 
    msdb.dbo.backupset.backup_start_date, 
    msdb.dbo.backupset.backup_finish_date, 
    msdb.dbo.backupset.expiration_date, 
    CASE msdb..backupset.type 
    WHEN 'D' THEN 'Database' 
    WHEN 'L' THEN 'Log' 
END AS backup_type, 
msdb.dbo.backupset.backup_size, 
msdb.dbo.backupmediafamily.logical_device_name, 
msdb.dbo.backupmediafamily.physical_device_name, 
msdb.dbo.backupset.name AS backupset_name, 
msdb.dbo.backupset.description 
FROM msdb.dbo.backupmediafamily 
INNER JOIN msdb.dbo.backupset ON msdb.dbo.backupmediafamily.media_set_id = msdb.dbo.backupset.media_set_id 
WHERE (CONVERT(datetime, msdb.dbo.backupset.backup_start_date, 102) >= GETDATE() - 7) 
ORDER BY 
msdb.dbo.backupset.database_name, 
msdb.dbo.backupset.backup_finish_date 

最后发现了。。别人的数据备份的在别人的数据上。。。

没碰到过，我的可以，帮顶一下。
