SQL Server 作业的备份(备份作业非备份数据库)

答案：作业备份，不是备份数据库，是备份作业。 

我的方法是把作业导出成文件备份起来，因为当你服务器维护的多了的时候很多你的作业 就很成问题，很麻烦。 

最好能够作业实现同步，这个也是第一步，保存成文件，之后个人设想使用powershell 来把作业同步起来 
复制代码 代码如下:
 
DECLARE @jobname VARCHAR(30),@category_calss_i INT ,@category_calss VARCHAR(50),@category_name VARCHAR(50) 
,@category_type VARCHAR(30),@category_id int 
,@category_type_i int 
SELECT @jobname = 'powershell',@category_calss = '',@category_name='',@category_type = '' 

SELECT @category_calss = CASE WHEN tshc.category_class = 1 THEN 'JOB' 
WHEN tshc.category_class = 2 THEN 'ALERT' 
else 'OPERATOR' 
END 
, @category_type = CASE WHEN tshc.category_type = 1 THEN 'LOCAL' 
WHEN tshc.category_type = 2 THEN 'MULTI-SERVER' 
else 'NONE' 
END 
,@category_name = tshc.name 
,@category_type_i = category_type 
,@category_calss_i = tshc.category_class 
,@category_id = tshc.category_id 
FROM 
msdb.dbo.sysjobs_view AS sv 
INNER JOIN msdb.dbo.syscategories AS tshc ON sv.category_id = tshc.category_id 
WHERE 
(sv.name=@jobname AND tshc.category_class = 1) 

PRINT ' BEGIN TRANSACTION'
