尝试从SQL Server备份数据时出错

Question

当我尝试在数据库中进行备份时，我遇到了令人不安和连续的错误。我已经完成了关于这个主题的研究，但我无法修复它。 请有知识的人，提出解决问题的最佳方法。以下是以下错误消息： 我试过更改.dll文件，没有机会！

Answer 1

你可以这样做一个自动脚本：

DECLARE @path VARCHAR(500)
DECLARE @name VARCHAR(500)
DECLARE @filename VARCHAR(256)
DECLARE @time DATETIME
DECLARE @year VARCHAR(4)
DECLARE @month VARCHAR(2)
DECLARE @day VARCHAR(2)
DECLARE @hour VARCHAR(2)
DECLARE @minute VARCHAR(2)
DECLARE @second VARCHAR(2)

-- 2. Setting the backup path

SET @path = 'D:\Backup\'  

 -- 3. Getting the time values

SELECT @time = GETDATE()
SELECT @year   = (SELECT CONVERT(VARCHAR(4), DATEPART(yy, @time)))
SELECT @month  = (SELECT CONVERT(VARCHAR(2), FORMAT(DATEPART(mm,@time),'00')))
SELECT @day    = (SELECT CONVERT(VARCHAR(2), FORMAT(DATEPART(dd,@time),'00')))
SELECT @hour   = (SELECT CONVERT(VARCHAR(2), FORMAT(DATEPART(hh,@time),'00')))
SELECT @minute = (SELECT CONVERT(VARCHAR(2), FORMAT(DATEPART(mi,@time),'00')))
SELECT @second = (SELECT CONVERT(VARCHAR(2), FORMAT(DATEPART(ss,@time),'00')))

-- 4. Defining cursor operations

DECLARE db_cursor CURSOR FOR  
SELECT name 
FROM master.dbo.sysdatabases 
WHERE name NOT IN ('master','model','msdb','tempdb')  -- system databases are excluded

--5. Initializing cursor operations

OPEN db_cursor   
FETCH NEXT FROM db_cursor INTO @name   

WHILE @@FETCH_STATUS = 0   
BEGIN

-- 6. Defining the filename format

       SET @fileName = @path + @name + '_' + @year + @month + @day + @hour + @minute + @second + '.BAK'  
       BACKUP DATABASE @name TO DISK = @fileName  


       FETCH NEXT FROM db_cursor INTO @name   
END   
CLOSE db_cursor   
DEALLOCATE db_cursor

然后将其放入SQL作业步骤并按照以下方式安排：

在SQL作业代理下创建新作业并添加新步骤

添加时间表

作业创建时间表
